Exact Asymptotic Expansion of Singular Solutions for the (2 + 1)‐D Protter Problem

Abstract: We study three-dimensional boundary value problems for the nonhomogeneous wave equation, which are analogues of the Darboux problems in R 2 . In contrast to the planar Darboux problem the three-dimensional version is not well posed, since its homogeneous adjoint problem has an infinite number of classical solutions. On the other hand, it is known that for smooth right-hand side functions there is a uniquely determined generalized solution that may have a strong power-type singularity at one boundary point. Thi… Show more

“…Necessary and sufficient conditions for the existence of solutions with fixed order of singularity were obtained in [10]. Similarly, for the R 3 -analogues of Protter problems, some results are presented in [13,14]. For the problem with Dirichlet type boundary condition on Σ 0 , a formula for the asymptotic expansion of the singular solution can be found in [15], and the semi-Fredholm solvability is discussed in [16] for ∈ 10 (Ω).…”
