Hermitian rank in ideal powers
Abdullah Al Helal, Jiří Lebl
We prove that the (hermitian) rank of is bounded from below by the rank of whenever is not identically zero and real-analytic in a neighborhood of some point on th…
Records from the S-Matrix Marathon: Tasty Bits of Several Complex Variables
Sean N. Curry, Jiří Lebl, Mathieu Giroux +3
We will cover the basics of several complex variables in 4 lectures: Basic properties of holomorphic functions in several variables, the notion of pseudoconvexity, CR functions and…
Variational Quantum Algorithms for Euclidean Discrepancy and Covariate-Balancing
Jiří Lebl, Asif Shakeel
Algorithmic discrepancy theory seeks efficient algorithms to find those two-colorings of a set that minimize a given measure of coloring imbalance in the set, its {\it discrepancy}…
Removing Isolated Zeroes by Homotopy
Adam Coffman, Jiří Lebl
Suppose that the inverse image of the zero vector by a continuous map has an isolated point . There is a local obstruction to removing this iso…
