Theoretical Physics: A Primer for Philosophers of Science

open access: yesPrincipia: An International Journal of Epistemology, 2009
We give a overview of the main areas in theoretical physics, with emphasis on their relation to Lagrangian formalism in classical mechanics. This review covers classical mechanics; the road from classical mechanics to Schrödinger’s quantum mechanics ...

Boundary effects in super-Yang–Mills theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
In this paper, we shall analyze a three dimensional supersymmetry theory with $$\mathcal {N} = 2$$ N = 2 supersymmetry. We will analyze the quantization of this theory, in the presence of a boundary.

THE APPLICATION OF LAGRANGIAN PARTICLE TRACKING TECHNIQUES TO MODELLING OF CONTAMINANTS IN WATER RESOURCES

open access: yesBoletim do Observatório Ambiental Alberto Ribeiro Lamego
The Lagrangian model is widely used to track particles in water resources. The model, primarily a stochastic deterministic solution, is coupled with virtual passive particles driven by hydrodynamic forces.

Continuous spin gauge field in (A)dS space

open access: yesPhysics Letters B, 2017
Totally symmetric continuous spin field propagating in (A)dS is studied. Lagrangian gauge invariant formulation for such field is developed. Lagrangian of continuous spin field is constructed in terms of double traceless tensor fields, while gauge ...

The Symmetries of Equivalent Lagrangian Systems and Constants of Motion [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2011
In this paper Mathematical structure of time-dependent Lagrangian systems and their symmetries are extended and the explicit relation between constants of motion and infinitesimal symmetries of time-dependent Lagrangian systems are considered.

Lagrangian vector field and Lagrangian formulation of partial differential equations

open access: yesCondensed Matter Physics, 2005
In this paper we consider the Lagrangian formulation of a system of second order quasilinear partial differential equations. Specifically we construct a Lagrangian vector field such that the flows of the vector field satisfy the original system of ...

Maslov index on symplectic manifolds infinitesimal Lagrangian manifolds

open access: yesСовременная математика: Фундаментальные направления
This paper is a summary of the report at the conference “Semiclassical analysis and nonlocal elliptic problems-2023”. The definition of the Maslov index of a Lagrangian manifold as a class of onedimensional cohomologies on it gave rise to numerous works ...

Review: Hydrocodes for Structural Response to Underwater Explosions

open access: yesShock and Vibration, 1999
The applicability of the various hydrocode methodologies (Lagrangian, Eulerian, Coupled Eulerian–Lagrangian, and Arbitrary Lagrangian–Eulerian) for structural response to underwater explosions is reviewed.
