Tropical rational curves with first order tangency via WDVV

Anantadulal Paul, Aditya Subramaniam

In this article, we study the tropical counterpart of the enumeration of rational curves in $CP^{2}$ with first order tangency. We use the tropical analogue of the WDVV tech…

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…

Seshadri constants of equivariant vector bundles on toric varieties

Jyoti Dasgupta, Bivas Khan, Aditya Subramaniam

We compute Seshadri constants of a torus equivariant nef vector bundle on a projective space satisfying certain conditions. As an application, we compute Seshadri constants of tang…

Bounded negativity and Harbourne constants on ruled surfaces

Krishna Hanumanthu, Aditya Subramaniam

Let $X$ be a smooth projective surface and let $C$ be an arrangement of curves on $X$ . The Harbourne constant of $C$ was defined as a way to investigate the occ…
