Many topological spaces including smooth manifolds and algebraic varieties can be triangulated, but the explicit triangulations are often unknown or too big to be of practical interest. We will take a look at this problem from the viewpoint of algebraic…

I will report on joint work with Robert Burklund in which we remove finiteness assumptions from a theorem of Mandell. Specifically, we show that the canonical functor from p-adic,nilpotent spaces to (E∞-) coalgebras over F¯p is fully faithful.

A linear operator on a Hilbert space is called Fredholm if its kernel and cokernel are finitedimensional. As was shown in classical works of Atiyah, J¨anich, and Singer, the space of bounded Fredholm operators represents even K-theory; its subspace consisting…

An (equivariant) symplectic…
