Isotopy invariance and stratified $E_{2}$ -structure of the Ran Grassmannian

Guglielmo Nocera, Morena Porzio

Let $G$ be a complex reductive group. A folklore result asserts the existence of an $E_{2}$ -algebra structure on the Ran Grassmannian of $G$ over $A_{C}^{1}$ …

On Modified Diagonal Cycles and the Beauville Decomposition of the Ceresa Cycle

Lucas Lagarde, Mohamed Moakher, Morena Porzio +2

Let $C$ be a curve of genus $g \geq 2$ , and let $J$ be its Jacobian. The choice of a degree 1 divisor $e$ on $C$ gives an embedding of $C$ into $J$ ; we denote by $[C]_{}^{e}\in \ma…

Density of algebraic points on products of curves

Jennifer Berg, Yu Fu, Evangelia Gazaki +3

In this paper, we initiate the systematic study of density of algebraic points on surfaces. We give an effective asymptotic range in which the density degree set has regular behavi…
