Local Euler Obstructions of Reflective Projective Varieties

Xiping Zhang

In this note we introduce the concept of reflective projective varieties. These are stratified projective varieties with certain dimension constraints on their dual varieties. We p…

Characteristic Classes of Homogeneous Essential Isolated Determinantal Varieties

Xiping Zhang

The (homogeneous) Essentially Isolated Determinantal Variety is the natural generalization of generic determinantal variety, and is fundamental example to study non-isolated singul…

Local Euler Obstruction and Chern-Mather classes of Determinantal Varieties

Xiping Zhang

For $m \geq n$ , Let $K$ be an algebraic closed base field, and define $τ_{m, n, k}$ to be the set of $m \times n$ matrices over $K$ with kernel dimension $\geq k$ . This is a projective…
