Moving curves and Seshadri constants
Andreas Leopold Knutsen, Wioletta Syzdek, Tomasz Szemberg
We study families of curves covering a projective surface and give lower bounds on the self-intersection of the members of such families, improving results of Ein-Lazarsfeld and Xu…

Seshadri constants and surfaces of minimal degree
Wioletta Syzdek, Tomasz Szemberg
In "Seshadri fibrations of algebraic surfaces" [arXiv:0709.2592v1] we showed that if the multiple point Seshadri constants of an ample line bundle on a smooth projective surface in…

Seshadri constants on surfaces of general type
Thomas Bauer, Tomasz Szemberg
We study Seshadri constants of the canonical bundle on minimal surfaces of general type. First, we prove that if the Seshadri constant $\eps(K_X,x)$ is between 0 and 1, then it is…
