Query: Morita cohomology   We consider two categorifications of the cohomology of a topological space X
by taking coefficients in the category of differential graded categories. We
consider both derived global sections of a constant presheaf and singular
cohomology and find the resulting dg-categories are quasi-equivalent and
moreover quasi-equivalent to representations in perfect complexes of chains on
the loop space of X.
