Abstract

For the equation \((\operatorname{sgn} y){{\left| y \right|}^{m}}{{u}_{{xx}}} + {{u}_{{yy}}} + {{\alpha }_{0}}{{\left| y \right|}^{{(m - 2)/2}}}{{u}_{x}} + ({{\beta }_{0}}{\text{/}}y){{u}_{y}} = 0,\) considered in some unbounded mixed domain, uniqueness and existence theorems are proved for a solution to the problem with the missing shift condition on the boundary characteristics and an analogue of the Frankl-type condition on the interval of degeneracy of the equation.

具有奇异系数的盖勒斯特方程的弗兰克尔和混合条件的类似问题
摘要对于方程 \((\operatorname{sgn} y){{\left| y \right|}^{m}}{{u}_{{xx}}}+ {{u}_{yy}}+ {{\alpha }_{0}}{{left| y \right|}^{(m-2)/2}}}{{u}_{x}}}。+ ({{\beta }_{0}}{text{/}}y){{u}_{y}}=0,\)考虑在某个无界混合域中,证明了问题解的唯一性和存在性定理,其中边界特征上有缺失移位条件,方程的退化区间上有类似的弗兰克尔型条件。
