In this survey we provide an overview of our recent results concerning Ricci de Turck flow on spaces with isolated conical singularities. The crucial characteristic of the flow is that it preserves the conical singularity. Under certain conditions, Ricci flat metrics with isolated conical singularities...

We prove that, if A is an algebra (over a field of characteristic zero) with no nonzero joint divisor of zero and containing a nonzero central idempotent, and if A satisfies the identities ( x p , x q , x r ) = 0 and ( x p ′ , x q ′ , x r ′ ) = 0 with exponents...
