Generalized Reflection Coefficients
I consider general reflection coefficients for arbitrary one-dimensional whole line differential or difference operators of order 2. These reflection coefficients are semicontinuous functions of the operator: their absolute value can only go down when limits are taken. This implies a corresponding semicontinuity result for the absolutely continuous spectrum, which applies to a very large class ...

متن کاملWeak-shock Reflection Factors
Ernst Mach (1838-1916) was the first to discover an irregular reflection phenomenon of shock waves, as is well known in our community. In fact, this occurred in 1875-three years earlier than usually assumed in the literature [1]. However, it is correct that Mach gave the physical interpretation of this phenomenon in 1878 [2]. Since Mach's discovery of an irregular shock reflection pattern some ...
متن کاملWeak reflection principle for Lévy processes
In this paper, we develop a new mathematical technique which can be used to express the joint distribution of a Markov process and its running maximum (or minimum) through the distribution of the process itself. This technique is an extension of the classical reflection principle for Brownian motion, and it is obtained by weakening the assumptions of symmetry required for the standard reflectio...
متن کاملSelf-Similar Solutions for Weak Shock Reflection
We present numerical solutions of a two-dimensional Riemann problem for the unsteady transonic small disturbance equations that provides an asymptotic description of the Mach reflection of weak shock waves. We develop a new numerical scheme to solve the equations in selfsimilar coordinates and use local grid refinement to resolve the solution in the reflection region. The solutions contain a re...
