El presente articulo analiza las repercusiones del pensamiento de G. Politzer en la filosofía de la vida elaborada por G. Canguilhem. Durante los primeros treinta años del siglo XX, los textos de Politzer brindan un material importante para la cons

El presente artículo establece un análisis relativo a los sentidos que organizan las narraciones de las políticas identitarias, considerando sus vínculos históricos y sociales con la dimensión de la violencia extrema. Para ello, se toman en cue

We discuss a procurement problem with transportation losses and piecewise linear production costs.We first provide an algorithm based on Knaster-Tarski's fixed point theorem to solve the allocationproblem in the quadratic losses case. We then identif

To study first-price procurement auctions in the presence of losses, we introduce a new fixed point gradient flow algorithm to compute the Bayesian Nash Equilibrium. We use this efficient algorithm to compare optimal, first-price and VCG auctions. Th

In this paper we study a pollution regulation problem in an electricity market with a network structure. The market is ruled by an independent system operator (ISO for short) who has the goal of reducing the pollutant emissions of the providers in th

In this paper, we propose dynamic sampled stochastic approximated (DS-SA) extragradient methods for stochastic variational inequalities (SVIs) that are robust with respect to an unknown Lipschitz c...

Our aim in this paper is to prove geometric characterizations of the free disposal condition for nonconvex economies on infinite dimensional commodity spaces even if the cone and the production set involved in the condition have an empty interior suc

We propose an extragradient method with stepsizes bounded away from zero for stochastic variational inequalities requiring only pseudo-monotonicity. We provide convergence and complexity analysis, allowing for an unbounded feasible set, unbounded ope

We propose dynamic sampled stochastic approximation (SA) methods for stochastic optimization with a heavy-tailed distribution (with finite 2nd moment). The objective is the sum of a smooth convex function with a convex regularizer. Typically, it is a
