This can be viewed as a rather complicated generalization of the following vaguely “cohomological”-looking observation: if one has some real numbers and some primes with for all , then one should have for some , where I am being vague here about what means (and why it might be useful ...
The tennis player problem is a microcosmic example of an abstract and pretty piece of mathematics. The example is bad because, although mathematicians are usually interested in things other than counting, it deals with counting; it's bad because it does not, cannot, exhibit any of the conceptua...

In contrast, we observe that, if we require that it be invariant under homological equivalence of differential coalgebras, there is no natural modeling of the comultiplication in the loop space. But, in rational homotopy theory, results of Milnor–Moore and Quillen show that there is a ...

HOMOLOGICAL algebraVirtual resolutions are homological representations of finitely generated Pic(X)-graded modules over the Cox ring of a smooth projective toric variety. In this paper, we identify two algebraic conditions that characterize when a chain complex of graded free modules over the Cox ring...
