Optical Properties Chern-Simons (3+1)D -systems
Luis Huerta
Chern-Simons (CS) -systems are described by a term in the action ( is an adimensional parameter), which does not change field equations in the bulk, but aff…
Speed selection and stability of wavefronts for delayed monostable reaction-diffusion equations
Abraham Solar, Sergei Trofimchuk
We study the asymptotic stability of traveling fronts and front's velocity selection problem for the time-delayed monostable equation $u_{t}(t,x) = u_{xx}(t,x) - u(t,x) + g(u…
Difference equation for the Heckman-Opdam hypergeometric function and its confluent Whittaker limit
J. F. van Diejen, E. Emsiz
We present an explicit difference equation for the Heckman-Opdam hypergeometric function associated with root systems. Via a confluent hypergeometric limit, an analogous difference…
Asymptotic convergence to pushed wavefronts in a monostable equation with delayed reaction
Abraham Solar, Sergei Trofimchuk
We study the asymptotic behaviour of solutions to the delayed monostable equation : with monotone reaction…
Branching Formula for Macdonald-Koornwinder Polynomials
J. F. van Diejen, E. Emsiz
We present an explicit branching formula for the six-parameter Macdonald-Koornwinder polynomials with hyperoctahedral symmetry.
Additive group actions on affine T-varieties of complexity one in arbitrary characteristic
Kevin Langlois, Alvaro Liendo
Let X be a normal affine T-variety of complexity at most one over a perfect field k, where T stands for the split algebraic torus. Our main result is a classification of additive g…
