Is there a topological description of combinatorial Euler characteristic?

the best approach to the geometric euler characteristic comes from the theory of o-minimal structures. the best reference in this area is the book "tame topology and o-minimal structures" by lou van …

Is there a topological description of combinatorial Euler characteristic?

a few comments on the comments above: the combinatorial euler characteristic of a definable space (roughly speaking, a space with finite decomposition into finite-dimensional cells) is a homeomophis …
