Non-commuting Variations in Mathematics and Physics

This text presentsand studies the method of so –called noncommuting variations in VariationalCalculus. This methodwas pioneered by Vito Volterra  whonoticed that the conventional Euler-Lagrange (EL-)  equations  are not applicable in Non-Holonomic Mechanicsand  suggested to modify the basic ruleused in Variational Calculus. This book presents a survey of   VariationalCalculus with non-commutative ...
