GW/DT invariants and 5D BPS indices for strips from topological recursion
Sibasish Banerjee, Alexander Hock, Olivier Marchal
Topological string theory partition function gives rise to Gromov-Witten invariants, Donaldson-Thomas invariants and 5D BPS indices. Using the remodeling conjecture, which connects…

Optimal sub-Gaussian variance proxy for 3-mass distributions
Soufiane Atouani, Olivier Marchal, Julyan Arbel
We investigate the problem of characterizing the optimal variance proxy for sub-Gaussian random variables,whose moment-generating function exhibits bounded growth at infinity. We a…

Optimal sub-Gaussian variance proxy for truncated Gaussian and exponential random variables
Mathias Barreto, Olivier Marchal, Julyan Arbel
This paper establishes the optimal sub-Gaussian variance proxy for truncated Gaussian and truncated exponential random variables. The proofs rely on first characterizing the optima…
