Generalizations of the Hilbert-Weierstrass theorem and Tonelli-Morrey theorem: The regularity of solutions of differential equations and optimal control problems
(Semnan University, 2025-08-01)One of the basic problems in the “Calculus of Variations" is the minimization of the following functional:$$F(x)=\int_a^b f(t,x(t),x'(t)) dt,$$over a class of functions $x$ defined on the interval $[a,b]$. According to a ...
