Topological Phenomena Protected by Diabolical Textures

Sayantan Mandal, Neelima Pulletikurty, Abhishodh Prakash

We present a new class of topological phenomena in inhomogeneous systems arising from the adiabatic spatial embedding of parametrized families of quantum states such as charge pump…

On the loci of morphisms from $P^{1}$ to $G (r, n)$ with fixed splitting type of the restricted universal sub-bundle or quotient bundle

Sayanta Mandal

Let $n \geq 4$ , $2 \leq r \leq n - 2$ and $e \geq 1$ . We show that the intersection of the locus of degree $e$ morphisms from $P^{1}$ to $G (r, n)$ with the restricted universal…

On the stabilization of the Betti numbers of the moduli space of sheaves on $P^{2}$

Sayanta Mandal

Let $r \geq 2$ be an integer, and let $a$ be an integer coprime to $r$ . We show that if $c_{2} \geq n + ⌊ \frac{r - 1}{2 r} a^{2} + \frac{1}{2} (r^{2} + 1) ⌋$ , then the…
