具有变速和局部化右端的二维wave equation渐近问题中的非交换算子函数
Functions of noncommuting operators in an asymptotic problem for a 2D wave equation with variable velocity and localized right-hand side
摘要:
我们使用非交换算子的函数理论(非交换分析)来解决一个偏微分方程的渐近问题,并展示如何从一般结构和算子公式开始,从微分方程的观点来看,这些公式似乎相当抽象,人们可以最终得到非常具体,易于评估的解表达式,有用的,例如,在海啸问题上。
英文摘要:
We use the theory of functions of noncommuting operators (noncommutative analysis) to solve an asymptotic problem for a partial differential equation and show how, starting from general constructions and operator formulas that seem to be rather abstract from the viewpoint of differential equations, one can end up with very specific, easy-to-evaluate expressions for the solution, useful, e.g., in the tsunami wave problem.
