Abstract
AbstractWe study sections of the generic determinantal varieties by generic hyperplanes of various codimensions , the polar multiplicities of these sections, and the cohomology of their real and complex links. Such complex links were shown to provide the basic building blocks in a bouquet decomposition for the (determinantal) smoothings of smoothable isolated determinantal singularities. The detailed vanishing topology of such singularities was still not fully understood beyond isolated complete intersections and a few further special cases. Our results now allow to compute all the cohomology with integer coefficients below the middle degree and the middle Betti number for any determinantal smoothing.
