Limiting absorption principle for the dissipative Helmholtz equation
This equation modelizes accurately the propagation of the electromagnetic field of a laser in material medium. Here k0 is the wave number of the laser in the vacuum, N and a are smooth nonnegative functions representing the electronic density of material medium and the absorption coefficient of the laser energy by material medium, and A0 is an incident known excitation (see [BLSS03]). Note that...

متن کاملApplications of He’s Variational Principle method and the Kudryashov method to nonlinear time-fractional differential equations
In this paper, we establish exact solutions for the time-fractional Klein-Gordon equation, and the time-fractional Hirota-Satsuma coupled KdV system. The He’s semi-inverse and the Kudryashov methods are used to construct exact solutions of these equations. We apply He’s semi-inverse method to establish a variational theory for the time-fractional Klein-Gordon equation, and the time-fractiona...
متن کاملThe Limiting Absorption Principle for a Periodic Semi-Infinite Waveguide
We study an elliptic boundary value problem in a semi-infinite, straight waveguide containing a periodic material distribution. The spectral parameter is taken to lie in a spectral band of the corresponding full-space periodic operator. In contrast to the situation with constant coefficients, it is not obvious how to define the “outgoing” solution of the problem. In order to define the outgoing...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
