Fundamental groups of highly symmetrical curves and Fermat line arrangments

Meirav Amram, Praveen Kumar Roy, Uriel Sinichkin

We showcase a computation of the fundamental group of $CP^{2} - C$ when $C$ is a curve admitting a lot of symmetries. In particular, let $C$ de…

Seshadri constants of curve configurations on surfaces

Krishna Hanumanthu, Praveen Kumar Roy, Aditya Subramaniam

Let $X$ be a complex nonsingular projective surface and let $L$ be an ample line bundle on $X$ . We study multi-point Seshadri constants of $L$ at singular points of certain arrange…

The fundamental group of Galois covers of surfaces with octahedral envelope

Meirav Amram, Cheng Gong, Praveen Kumar Roy +2

We compute the fundamental group of the Galois cover of a surface of degree~ $8$ , with singularities of degree $4$ , whose degeneration envelope is isomorphic to an octahedron. The g…
