Bogdan Bojarski, Andrzej Weber
We define certain class of correspondences of polarized representations of -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…

Generalized Riemann-Hilbert Transmission and Boundary Value Problems, Fredholm Pairs and Bordisms
Bogdan Bojarski, Andrzej Weber
We present classical and generalized Riemann-Hilbert problem in several contexts arising from -theory and bordism theory. The language of Fredholm pairs turns out to be useful a…
