Einstein metrics and the number of smooth structures on a four-manifold

V. Braungardt, D. Kotschick

We prove that for every natural number k there are simply connected topological four-manifolds which have at leat k distinct smooth structures supporting Einstein metrics, and also…

Clustering of critical points in Lefschetz fibrations and the symplectic Szpiro inequality

V. Braungardt, D. Kotschick

We prove upper bounds for the number of critical points in semistable symplectic Lefschetz fibrations. We also obtain a new lower bound for the number of nonseparting vanishing cyc…
