Radiation Condition and Limiting Amplitude Principle for Acoustic Propagators with Two Unbounded Media

, 1996
Consider the diffraction problem for perturbed acoustic propagators with perturbations decreasing slowly at infinity. The propagation speed is discontinuous at the interface of two unbounded media, and the interface may be an arbitrary and smooth surface

Self-averaging from lateral diversity in the ItôSchrödinger equation

, 2006
. We consider the random Schrödinger equation as it arises in the paraxial regime for wave propagation in random media. In the white noise limit it becomes the Itô-Schrödinger stochastic partial differential equation (SPDE) which we analyze here in the ...

Сингулярни решения с експоненциален ръст за четиримерното вълново уравнение

, 2011
Недю И. Попиванов, Тодор П. Попов, Рудолф Шерер - Разглеждат се четиримерни гранични задачи за нехомогенното вълново уравнение. Те са предложени от М. Протер като многомерни аналози на задачата на Дарбу в равнината.
