Description of Nonlinear Phenomena in the Atmospheric Dynamics through Linear Wave type Equations
Rodica Cimpoiasu, Radu Constantinescu
The paper takles a procedure which allow to extend some linear, wave type equations to the study of nonlinear models. More concretely, we present a practical way to generate the la…
Extended BRST symmetries. Quantum approach
Radu Constantinescu, Carmen Ionescu
The aim of this lecture is to present in a comprehensible way what the BRST quantization means and how the "classical" master equation, action and BRST transformations have to be p…
Generalized evolutionary equations with imposed symmetries
Rodica Cimpoiasu, Radu Constantinescu
The paper proposes an algorithm which could identify a general class of pdes describing dynamical systems with similar symmetries. The way that will be followed starts from a given…
Symmetries, Integrability and Exact Solutions for Nonlinear Systems
Rodica Cimpoiasu, Radu Constantinescu
The paper intends to offer a general overview on what the concept of integrability means for a nonlinear dynamical system and how the symmetry method can be applied for approaching…
