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. |
