There is a proposition due to Koll\'ar 1997 on computing log canonical thresholds of certain hypersurface germs using weighted blowups, which we extend to weighted blowups with non-negative weights. Using this, we show that the log…

We construct a solution for the Complex Ginzburg-Landau (CGL) equation in a general critical case, which blows up in finite time T only at one blow-up point. We also give a sharp description of its profile.

We present an analytic proof of the relationship between the Calabi-Futaki invariant for a K\"ahler manifold relative to a holomorphic vector field with a nondegenerate zero and the corresponding invariant of its blowup at that zero,…
