Recently, there appeared a significant interest in inverse spectral problems for non-local operators arising in numerous applications. In the present work, we consider the operator with frozen argument $ly = -y''(x) + p(x)y(x) + q(x)y(a)$, which is a

The class of generalized $ SD{D_1} \; \left({GSD{D_1}} \right) $ matrices is a new subclass of $ H $-matrices. In this paper, we focus on the subdirect sum of $ GSD{D_1} $ matrices, and some sufficient conditions to ensure that the subdirect sum of $

Applying a parametric approach, in this paper we studied a new class of multidimensional extremization models with data uncertainty. Concretely, first, we derived the robust conditions of necessary optimality. Thereafter, we established robust suffic
