Lagrangians, Gauge Functions, and Lie Groups for Semigroup of Second-Order Differential Equations
A set of linear second-order differential equations is converted into a semigroup, whose algebraic structure is used to generate novel equations. The Lagrangian formalism based on standard, null, and nonstandard Lagrangians is established for all members of the semigroup. For the null Lagrangians, t...
