非局部边界条件下具有原子测度的Feller半群的存在性

On the existence of a Feller semigroup with atomic measure in nonlocal boundary condition

Pavel Gurevich

摘要:

研究了多维扩散过程理论中Feller半群的存在性。考虑平面有界区域$G$上的二阶椭圆算子.它的定义域由满足区域边界上的非局部条件的连续函数组成。一般来说,非局部项是函数在区域$G$关于非负Borel测度$μ(y,dη)$,$y\in\partial G$的闭包上的积分。证明了在测度是原子测度的情况下,该算子是Feller半群的生成元。这一措施的微小性并不是假定的。

英文摘要:

The existence of Feller semigroups arising in the theory of multidimensional diffusion processes is studied. An elliptic operator of second order is considered on a plane bounded region $G$. Its domain of definition consists of continuous functions satisfying a nonlocal condition on the boundary of the region. In general, the nonlocal term is an integral of a function over the closure of the region $G$ with respect to a nonnegative Borel measure $μ(y,dη)$, $y\in\partial G$. It is proved that the operator is a generator of a Feller semigroup in the case where the measure is atomic. The smallness of the measure is not assumed.
