Lagrangian and non-Lagrangian approaches to electrodynamics including supersymmetry
AIP Conference Proceedings, 2007We take a general approach to nonlinear electrodynamics that includes non‐Lagrangian as well as Lagrangian theories. We introduce the constitutive tensors which, together with Maxwell's equations, describe nonlinear electrodynamics in an extremely general way.

An MDD-Based Lagrangian Approach to the Multicommodity Pickup-and-Delivery TSP
INFORMS journal on computing, 2019We address the one-to-one multicommodity pickup-and-delivery traveling salesman problem, a challenging variant of the traveling salesman problem that includes the transportation of commodities between locations.

Logicoalgebraic approach to Lagrangian systems
International Journal of Theoretical Physics, 1983A logicoalgebraic approach to the geometry of Lagrangian systems is pursued by starting axiomatically with a classical mechanical system whose logic is a separable and atomic Boolean σ algebra.

Lagrangian approach for dark solitons
Optics Communications, 1995We propose a variational formalism for dark solitons based on a nontrivial modification of the standard Lagrangian of the nonlinear Schrodinger equation. Our approach allows to consider a variety of asymptotically nonvanishing localised solutions for applying a variational technique together with the correct definition of momentum and energy.

Lagrangian Approach for Bounded Plasmas
Physica Scripta, 2004Lagrangian variables are used to describe both surface and volume nonlinear oscillations of spatially bounded plasmas. Simple exact, or nonperturbative, solutions can often be obtained for complicated problems. Here, several recent analytical results on nonlinear standing waves in bounded systems are reviewed.
