We pub­lish sci­entif­ic and re­search lit­er­at­ure of the highest qual­ity at the low­est sus­tain­able prices, cov­er­ing math­em­at­ics and oth­er se­lec­ted fields. Our out­stand­ing ed­it­or­i­al boards and highly se­lect­ive peer-re­view work­flows guar­an­tee the im­pact of the art­icles we pub­lish.

The Best Presentation

Top-level re­search de­serves top-level pro­duc­tion: we provide the highest qual­ity of math­em­at­ic­ally lit­er­ate copy­ed­it­ing in the in­dustry. Please read a few testi­mo­ni­als from our sat­is­fied au­thors.

Tunisian Journal of Mathematics NEW

msp.​org/​tunis  

The Tunisi­an Journ­al of Math­em­at­ics is an in­ter­na­tion­al pub­lic­a­tion or­gan­ized by the Tunisi­an Math­em­at­ic­al So­ci­ety and pub­lished in elec­tron­ic and print formats by MSP in Berke­ley. It is at­tract­ing ex­cel­lent pa­pers in all areas of math­em­at­ics, thanks to its first-rate in­ter­na­tion­al ed­it­or­i­al board. Art­icles are se­lec­ted based on out­stand­ing qual­ity and in­terest, and ac­cord­ing to the highest stand­ards.

Since its found­ing in 1992, the Tunisi­an Math­em­at­ic­al So­ci­ety has been a key stim­u­lus for high-level math­em­at­ics re­search in Tunisia and the sur­round­ing re­gion. The cre­ation of TJM mir­rors the So­ci­ety's in­teg­ra­tion in, and sup­port by, the in­ter­na­tion­al math­em­at­ics com­munity. As the journ­al's pub­lish­er, MSP will help con­trib­ute to the So­ci­ety's mis­sion of fos­ter­ing sci­entif­ic activ­ity on the Afric­an con­tin­ent.

The TJM ed­it­or­i­al board in­vites math­em­aticians from all over the world to take part in this stim­u­lat­ing pro­ject by sub­mit­ting high-level re­search art­icles.

The first TJM art­icles were pub­lished in 2018 (with a 2019 cov­er date). Con­tact us or send us an email if in­ter­ested in sub­scrib­ing.

Annals of K-Theory

msp.​org/​akt  

The An­nals of K-The­ory wel­comes ex­cel­lent re­search pa­pers in all areas of K-the­ory in its many forms. These may in­clude either fun­da­ment­al de­vel­op­ments in the core tech­niques and ideas, or else ap­plic­a­tions to oth­er sub­jects.

The An­nals of K-The­ory has been es­tab­lished to serve as the premi­er journ­al in K-the­ory and as­so­ci­ated areas of math­em­at­ics. These in­clude areas of al­geb­ra­ic geo­metry, ho­mo­lo­gic­al al­gebra, cat­egory the­ory, geo­metry, func­tion­al ana­lys­is, and al­geb­ra­ic to­po­logy, en­com­passing such top­ics as cyc­lic ho­mo­logy, mo­tivic ho­mo­topy the­ory, KK-the­ory, in­dex the­ory, and more. The journ­al wel­comes strong sub­mis­sions in all areas in which K-the­ory con­cepts or meth­od­o­logy play a role.

AKT is led by a pres­ti­gi­ous ed­it­or­i­al board, mainly former mem­bers of the board of the Journ­al of K-The­ory. It is pub­lished by MSP and owned by the K-The­ory Found­a­tion, whose pro­jects in­clude prizes for young math­em­aticians and spon­sor­ship of sci­entif­ic con­fer­ences and sum­mer schools.

AKT pub­lishes 4 is­sues per year, and aims to even­tu­ally reach 1,000 pages per year.

The K-The­ory Found­a­tion ac­know­ledges the pre­cious sup­port of Found­a­tion Com­posi­tio Math­em­at­ica, whose help has been in­stru­ment­al in the launch of the An­nals of K-The­ory.

Involve your students in research
msp.​org/​involve  

In­volve show­cases and en­cour­ages high-qual­ity math­em­at­ic­al re­search in­volving stu­dents from all aca­dem­ic levels. The ed­it­or­i­al board con­sists of math­em­at­ic­al sci­ent­ists com­mit­ted to nur­tur­ing stu­dent par­ti­cip­a­tion in re­search.

Sub­mis­sions in all math­em­at­ic­al areas are en­cour­aged. All manuscripts ac­cep­ted for pub­lic­a­tion in In­volve are con­sidered pub­lish­able in qual­ity journ­als in their re­spect­ive fields, and in­clude a min­im­um of one-third stu­dent au­thor­ship. Sub­mis­sions should in­clude sub­stan­tial fac­ulty in­put; fac­ulty co-au­thor­ship is en­cour­aged.

Bridging the gap between the ex­tremes of purely un­der­gradu­ate-re­search journ­als and main­stream re­search journ­als, In­volve provides a ven­ue to math­em­aticians wish­ing to en­cour­age the cre­at­ive in­volve­ment of stu­dents. In­volve is a great re­source for in­spir­ing math­em­at­ic­al ex­plor­a­tion in a new gen­er­a­tion, and an op­por­tun­ity for stu­dents who are ser­i­ous about their re­search.

JoMMS cov­ers the de­vel­op­ment of new tech­no­lo­gies, which re­quire mul­tidiscip­lin­ary sim­u­la­tion and draw from all areas of en­gin­eer­ing, ma­ter­i­als, and bio­logy.

Foun­ded by Charles R. Steele and Mar­ie-Louise Steele, JoMMS has had in mind from the be­gin­ning the needs of the aca­dem­ic and en­gin­eer­ing com­munit­ies it serves. Thor­ough ref­er­ee­ing en­sures high stand­ards, and skilled edit­ing after ac­cept­ance helps com­mu­nic­a­tion by non-nat­ive Eng­lish speak­ers — a ser­vice that most pub­lish­ers have dis­con­tin­ued.

Journal of Software for Algebra and Geometry

msp.​org/​jsag  

JSAG is an elec­tron­ic-only journ­al de­voted to short art­icles on soft­ware re­lated to re­search in al­gebra and geo­metry. Each short art­icle (typ­ic­ally not to ex­ceed five prin­ted pages, in­clud­ing ref­er­ences) will be ac­com­pan­ied by the ap­pro­pri­ate source code. The aim is to pro­mote the de­vel­op­ment of good code and free soft­ware for the math­em­at­ic­al re­search com­munity. Based on peer-re­view re­ports and tech­nic­al re­ports, the art­icles are ac­cep­ted or re­jec­ted by the ed­it­or­i­al board through a pro­cess of on­line dis­cus­sion and con­sensus.

Mathematics and Mechanics of Complex Systems

msp.​org/​memocs  

MEMOCS is a free and open-ac­cess, no-au­thor-fee, peer-re­viewed journ­al.

MEMOCS is a pub­lic­a­tion of the In­ter­na­tion­al Re­search Cen­ter for the Math­em­at­ics and Mech­an­ics of Com­plex Sys­tems at the Uni­versità dell’Aquila (Italy). It pub­lishes art­icles from di­verse sci­entif­ic fields with a spe­cif­ic em­phas­is on mech­an­ics. Art­icles must rely on the ap­plic­a­tion or de­vel­op­ment of rig­or­ous math­em­at­ic­al meth­ods.

The journ­al in­tends to foster a mul­tidiscip­lin­ary ap­proach to know­ledge firmly based on math­em­at­ic­al found­a­tions. It will serve as a for­um where sci­ent­ists from dif­fer­ent dis­cip­lines meet to share a com­mon, ra­tion­al vis­ion of sci­ence and tech­no­logy. It in­tends to sup­port and di­vulge re­search whose primary goal is to de­vel­op math­em­at­ic­al meth­ods and tools for the study of com­plex­ity.

The journ­al will also foster and pub­lish ori­gin­al re­search in re­lated areas of math­em­at­ics of proven ap­plic­ab­il­ity, such as vari­ation­al meth­ods, nu­mer­ic­al meth­ods, and op­tim­iz­a­tion tech­niques. Be­sides their in­trins­ic in­terest, such treat­ments can be­come heur­ist­ic and epi­stem­o­lo­gic­al tools for fur­ther in­vest­ig­a­tions, and provide meth­ods for de­riv­ing pre­dic­tions from pos­tu­lated the­or­ies. Pa­pers fo­cus­ing on and cla­ri­fy­ing as­pects of the his­tory of math­em­at­ics and sci­ence are also wel­come. All meth­od­o­lo­gies and points of view, if rig­or­ously ap­plied, will be con­sidered.

The Fine Print

Elec­tron­ic ac­cess to past is­sues of a journ­al is in­cluded with every sub­scrip­tion to that journ­al, as long as a sub­scrip­tion is main­tained. Per­petu­al ac­cess is avail­able through the Glob­al LOCKSS Net­work.

Sub­scribers are asked to sign MSP’s Elec­tron­ic Journ­al Li­cense Agree­ment upon ini­ti­at­ing their sub­scrip­tion. After it is ini­tially signed, the EJLA will re­main in ef­fect as long as sub­scrip­tion fees are paid for at least one journ­al, un­less ter­min­ated in the man­ner provided in the EJLA. In oth­er words, a sub­scriber may need to sign the EJLA only once, as long as a sub­scrip­tion is main­tained from year to year.

We do not of­fer print-only sub­scrip­tions, only elec­tron­ic and elec­tron­ic+print. Sub­scrip­tions are offered for the cal­en­dar year only. Elec­tron­ic ac­cess al­lowed based on sub­mit­ted IP-ad­dress range. Sep­ar­ate cam­puses of an in­sti­tu­tion that are not with­in the same city or geo­graph­ic­ally close must be covered by sep­ar­ate sub­scrip­tions, or might be eli­gible for con­sor­ti­um pri­cing, at MSP’s dis­cre­tion.

All art­icles pub­lished by MSP be­come free to ac­cess and read after five years past pub­lic­a­tion (mean­ing on the fifth Janu­ary 1st after the pub­lic­a­tion date). The journ­als MEMOCS and JSAG are im­me­di­ately free to read, without any au­thor changes.
