RT journal article T1 The continuous-time problem with interval-valued functions: applications to economic equilibrium A1 Ruiz Garzón, Gabriel A1 Osuna Gómez, Rafaela A1 Rufián Lizana, Antonio A1 Chalco-Cano, Yurilev A2 Estadística e Investigación Operativa K1 Interval analysis K1 continuous-time programming problems K1 variational-like inequality problem K1 multiobjective optimization K1 economic application AB The aim of this paper is to define the Continuous-Time Problemin an interval context and to obtain optimality conditions for thisproblem. In addition, we will find relationships between solutionsof Interval Continuous-Time Problem (ICTP) and Interval VariationallikeInequality Problems, both Stampacchia and Minty type. Pseudoinvex monotonicity condition ensures the existence of solutionsof the (ICTP) problem. These results generalize similar conclusionsobtained in Euclidean or Banach spaces inside classical mathematicalprogramming problems or Continuous-Time Problems. We will finishgeneralizing the existence of Walrasarian equilibrium price modeland the Wardrop’s principle for traffic equilibrium problem to anenvironment of interval-valued functions.
