Euler Characteristic of Fredholm Quasicomplexes
N. N. Tarkhanov University of Potsdam
Abstract:
By quasicomplexes are usually meant perturbations of complexes small in some sense. Of interest are not only perturbations within the category of complexes but also those going beyond this category. A sequence perturbed in this way is no longer a complex, and so it bears no cohomology. We show how to introduce Euler characteristic for small perturbations of Fredholm complexes.
Keywords:
essential complexes, Fredholm complexes, Euler characteristic.
