Abstract
We consider multidimensional integral operators with bihomogeneous and rotation invariant kernels. For such operators we obtain a criterion for applicability of a projection method in the scalar and matrix cases and describe the limit behavior of the ε-pseudospectra of the truncated operators \(A_{\tau _1 , \tau _2 } \) as τ 1 → 0 and τ 2 → 0.
