Secondary cup and cap products in coarse geometry
Christopher Wulff
We construct secondary cup and cap products on coarse (co-)homology theories from given cross and slant products. They are defined for coarse spaces relative to weak generalized co…

Bordism Invariance of the Coarse Index
Christopher Wulff
We prove bordism invariance of the coarse index of complex elliptic pseudodifferential operators. In our discussion we introduce directed -bordisms, whose usefulness is illustra…
