摘要

摘要 本文研究了抛物-双曲混合型模型方程的直接问题和逆问题。在直接问题中,我们考虑了该方程的 Tricomi 问题的类似问题,其特征线类型发生了变化。逆问题的未知数是抛物线方程的 y 依赖源函数。为了确定它与定义在抛物线部分域中的解的关系,在点\(x=x_{0}\)处指定了一个\(y>0\)条件的过度确定。证明了在经典解的意义上所提出问题的唯一可解性的局部定理。

Determining a Source Function in the Mixed Parabolic–Hyperbolic Equation with Characteristic Type Change Line

Abstract

In this paper, we study the direct and inverse problems for a model equation of a mixed parabolic-hyperbolic type. In the direct problem, an analog of the Tricomi problem for this equation with a characteristic line of type change is considered. The unknown of the inverse problem is the y-dependent source function of the parabolic equation. To determine it with respect to the solution defined in the parabolic part of the domain, an overdetermination at the point \(x=x_{0}\) for \(y>0\) condition is specified. Local theorems on the unique solvability of the problems posed in the sense of the classical solution are proved.
