研究了在有界区域边界上简并的阶椭圆方程。在局部坐标系中，引入点的邻域，其中的算子给出，，。对于算子退化为拟椭圆算子，我们特别研究了椭圆算子转化为抛物算子的情况。参考书目19项。3数据。
We investigate the elliptic equation of order , degenerate on the boundary of a bounded domain . In local coordinates , introduced in a neighborhood of the point and in which is given by , the operator where , , . For the operator degenerates into the quasi-elliptic operator In particular we study the case of transition, for , of an elliptic operator into a parabolic operator.Bibliography 19 items. 3 figures.
