We present our talk at the round table discussion at the Hypercomplex Seminar 2016 (Będlewo, Poland). The note describes an inspiration related with elementary models of unbounded Jacobi martices with with a few bounded...
Application of Jacobi polynomials to approximate solution of a complete singular integral equation with Cauchy kernel on the real half-line
Jacobi polynomials are used to derive approximate solutions of the complete singular integral equation with Cauchy–type kernel defined on the real half–line in the case of constant complex coefficients. Moreover, estimat...
On optimal subspaces for Kolmogorov widths of classes of 2π-periodic analytic functions
The following problem arises: to nd optimal subspaces for Kolmogorov widths of classes of convolutions with generated kernels, which may increase the oscillations.
