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 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…
