Versal determinantal deformations

Mary Elizabeth Schaps

Vol. 107 (1983), No. 1, 213–221
Abstract

The paper investigates the deformations of a determinantal scheme arising from a deformation of the defining matrix. A sufficient condition is given for the parameter space of the versal deformation space to contain a unique smooth subscheme parameterizing determinantal deformations. Examples are given in which various determinantal representations of a scheme give different determinantal deformation spaces.
