Integral Deligne Cohomology for Real Varieties
Pedro F. dos Santos, Paulo Lima-Filho
We develop an integral version of Deligne cohomology for smooth proper real varieties. For this purpose the role played by singular cohomology in the complex case has to be replace…

On secant varieties of Compact Hermitian Symmetric Spaces
J. M. Landsberg, Jerzy Weyman
We show that the secant varieties of rank three compact Hermitian symmetric spaces in their minimal homogeneous embeddings are normal, with rational singularities. We show that the…

General isotropic flags are general (for Grassmannian Schubert calculus)
Frank Sottile
We show that general isotropic flags for odd-orthogonal and symplectic groups are general for Schubert calculus on the classical Grassmannian in that Schubert cells defined by such…
