Generalized Riemann-Hilbert Transmission and Boundary Value
Problems, Fredholm Pairs and Bordisms
Bogdan Bojarski and Andrzej Weber
We present classical and generalized Riemann-Hilbert problem in several
contexts arising from $K$-theory and bordism theory. The language of
Fredholm pairs turn out to be useful and unavoidable. We propose an
abstract formulation of a notion of bordism in the context of Hilbert
spaces equipped with splittings.
