AI总结:

本文研究了二维楔形中带有Robin边界条件的热方程的适定性与正则性,通过构建数学框架实现了任意高正则性,无需假设楔形开口角的大小。

摘要:

在无界二维楔形中,建立了带有Robin边界条件的热方程在单调加权L²空间下的适定性与更高正则性。所发展的数学框架允许在不假设楔形开口角小的情况下获得任意高的正则性。挑战在于解析子问题表现出两种缩放不变性的破坏,一种在方程中,一种在边界条件中。

英文摘要:

Well-posedness and higher regularity of the heat equation with Robin boundary conditions in an unbounded two-dimensional wedge is established in an $L^{2}$-setting of monomially weighted spaces. A mathematical framework is developed which allows to obtain arbitrarily high regularity without a smallness assumption on the opening angle of the wedge. The challenging aspect is that the resolvent problem exhibits two breakings of the scaling invariance, one in the equation and one in the boundary condition.
