On torsion in homology of singular toric varieties

Andrzej Weber

Let $X$ be a toric variety. Rationally Borel-Moore homology of $X$ is isomorphic to the homology of the Koszul complex $A^T_*(X)\otimes Λ^\x M$, where $A_{*}^{T} (X)$ is the equivariant…

Correspondences and index

Bogdan Bojarski, Andrzej Weber

We define certain class of correspondences of polarized representations of $C^{*}$ -algebras. Our correspondences are modeled on the spaces of boundary values of elliptic operators on…

Weights in cohomology and the Eilenberg-Moore spectral sequence

Matthias Franz, Andrzej Weber

We show that in the category of complex algebraic varieties, the Eilenberg--Moore spectral sequence can be endowed with a weight filtration. This implies that it degenerates if all…
