摘要

本文考虑积分几何问题,将其转化为一组满足正则性条件的曲线的混合型方程的差分问题。积分几何问题的独特类似问题的研究有其自身的复杂之处,因为对于独立导数的有限独特类似问题,其主要关系是在一个离散变量上进行一定的位移。因此,在转换为离散模拟时,以连续表示获得的许多关系呈现出更复杂的形式,并且需要对转换期间发生的连接器进行进一步研究。由于这些问题在一般情况下没有解的存在性定理,因此使用条件正确性的概念,也就是说,假定积分几何问题及其微分-微分类似问题有解。本文采用地质层析成像、医学层析成像、缺陷镜等方法对所得混合型方程边界问题的微分模拟进行了稳定性评价,证明了数值求解方法的紧凑性。

STABILITY OF THE DIFFERENTIAL-DIFFERENCE ANALOG OF THE INTEGRAL GEOMETRY PROBLEM WITH A WEIGHT FUNCTION
In this paper, we consider the problem of Integral geometry, which is brought to the problem of difference for a mixed-type equation for a bunch of curves that satisfy some regularity conditions. The study of distinctive analogues of Integral geometry problems has its own complex points, due to the fact that for limited-distinctive analogues of independent derivatives, the main relations are carried out with a certain shift over a discrete variable. Therefore, many relationships obtained in continuous representation take on a more complex form when switching to a discrete analog, and require further research on the connectors that occur duringthe shift. Since these problems do not have a theorem on the existence of a solution in the general case, the concept of conditional correctness is used, that is, it is assumed that the problem of Integral geometry and its differential-differential analoghave a solution. The stability assessment of the differential analog of the boundary problem for the mixed-type equation obtained in the work is carried out by geotomography, medical tomography, defectoscopy, etc. it is used to justify the compactness of numerical problem solving methods.
