Families of skew-symmetric matrices of even size
J. W. Bruce, V. V. Goryunov, G. J. Haslinger
The main result of the paper is a classification of singularities of complex skew-symmetric matrix families of even size which are simple under a natural equivalence relation. The…

Tjurina and Milnor numbers of matrix singularities
Victor Goryunov, David Mond
In order to understand the deformations of determinants and Pfaffians resulting from deformations of matrices, we study the deformation theory of composites , with isolat…
