Extragradient method with variance reduction for stochastic variational inequalities

AN Iusem, A Jofré, RI Oliveira, P Thompson - SIAM Journal on Optimization, 2017 - SIAM
We propose an extragradient method with stepsizes bounded away from zero for stochastic
variational inequalities requiring only pseudomonotonicity. We provide convergence and …

[LIBRO][B] Uncertainty quantification in variational inequalities: theory, numerics, and applications

An invariance principle for the 2d weakly self-repelling Brownian polymer

G Cannizzaro, H Giles - Probability Theory and Related Fields, 2025 - Springer
We investigate the large-scale behaviour of the Self-Repelling Brownian Polymer (SRBP) in
