High-order optimality conditions for degenerate variational problems

The paper is devoted to the class of singular calculus of variations problems with constraints which are not regular mappings at the solution point. Methods of the pp-regularity theory are used for investigation of isoperimetric and Lagrange singular problems. Necessary conditions for optimality in pp-regular calculus of variations problem are presented.
