Interaction between groundwater and surface water: proceedings of the symposium, held in Ystad, Sweden, May 30-June 3, 1988
摘要
This paper generalizes the optimality condition expressed by the Euler-Lagrange equation for classical calculus of variations. In the case of conjunctive management the generalized Euler-Lagrange equation is an integral equation or integral equation inequality.
