Cohomology of line bundles on the incidence correspondence
Zhao Gao, Claudiu Raicu
For a finite dimensional vector space V of dimension n, we consider the incidence correspondence (or partial flag variety) X in P(V) x P(V*), parametrizing pairs consisting of a po…
Borel-Moore homology of determinantal varieties
András C. Lőrincz, Claudiu Raicu
We compute the rational Borel-Moore homology groups for affine determinantal varieties in the spaces of general, symmetric, and skew-symmetric matrices, solving a problem suggested…
Euler obstructions for the Lagrangian Grassmannian
Paul LeVan, Claudiu Raicu
We prove a case of a positivity conjecture of Mihalcea-Singh, concerned with the local Euler obstructions associated to the Schubert stratification of the Lagrangian Grassmannian L…
Local Euler obstructions for determinantal varieties
András C. Lőrincz, Claudiu Raicu
The goal of this note is to explain a derivation of the formulas for the local Euler obstructions of determinantal varieties of general, symmetric and skew-symmetric matrices, by s…
Regularity of S_n-invariant monomial ideals
Claudiu Raicu
For a polynomial ring S in n variables, we consider the natural action of the symmetric group S_n on S by permuting the variables. For an S_n-invariant monomial ideal I in S and j…
Feasibility criteria for high-multiplicity partitioning problems
Claudiu Raicu
For fixed weights w_1,...,w_n, and for d>0, we let B denote a collection of d*n balls, with d balls of weight w_i for each i=1,...,n. We consider the problem of assigning the balls…
