Abstract: | We study the limit behavior of the spectral characteristics of truncated multidimensional integral operators whose kernels are homogeneous of degree –n and invariant under the rotation group SO(n). We prove that the limit of the -pseudospectra of the truncated operators K
as 0 is equal to the union of the -pseudospectra of the original operator K and the transposed operator
