Abstract:

We study the asymptotic distribution of eigenvalues of integral operators T k defined by kernels k which belong to Triebel-Lizorkin function space F p u σ ( F     q v τ ) by using the factorization theorem and the Weyl numbers x n . We use the relation between Triebel-Lizorkin space F p u σ ( Ω ) and Besov space B p q τ ( Ω ) and the interpolation methods to get an estimation for the distribution of eigenvalues in Lizorkin spaces F p u σ ( F     q v τ ) .
