Second order symmetry operators
Using systematic calculations in spinor language, we obtain simple descriptions of the second order symmetry operators for the conformal wave equation, the Dirac-Weyl equation and the Maxwell equation on a curved four dimensional Lorentzian manifold. The conditions for existence of symmetry operators for the different equations are seen to be related. Computer algebra tools have been developed ...
متن کاملKernel Asymptotics of Exotic Second-Order Operators
The Navier–Lamé operator of classical elasticity, μ∆v+(λ+μ)∇(∇·v), is the simplest example of a linear differential operator whose second-order terms involve a coupling among the components of a vector-valued function. Similar operators on Riemannian manifolds arise in conformal geometry and in quantum gravity. (In the latter context they have come to be called “nonminimal”, but “exotic” is pro...
متن کاملApplication of the Lie Symmetry Analysis for second-order fractional differential equations
Obtaining analytical or numerical solution of fractional differential equations is one of the troublesome and challenging issue among mathematicians and engineers, specifically in recent years. The purpose of this paper Lie Symmetry method is developed to solve second-order fractional differential equations, based on conformable fractional derivative. Some numerical examples are presented to il...
متن کاملCarleman estimates with second large parameter for second order operators
In this paper we prove Carleman type estimates with two large parameters for general linear partial differential operators of second order. By using second large parameter we derive from results for scalar equations first Carleman estimates for dynamical Lamé system with residual stress. We apply these estimates to obtain a Hölder and Lipschitz stability estimates of continuation of solutions o...
متن کاملinduced operators on symmetry classes of polynomials
in this paper, we give a necessary and sufficient condition for the equality of two symmetrized decomposable polynomials. then, we study some algebraic and geometric properties of the induced operators over symmetry classes of polynomials in the case of linear characters.
