Convergence of commutator of linear integral operators with separable kernel representing monomial covariance type commutation relations in $L_p$

Representations by linear integral operators on $L_p$ spaces over measure spaces are investigated for the polynomial covariance type commutation relations and more general two-sided generalizations of covariance commutation relations extending simultaneously the covariance and the reciprocal covariance type commutation relations. Necessary and sufficient conditions for the defining kernels of the integral operators are obtained for the operators to satisfy such commutation relations associated to pairs of polynomials. Representations by integral operators are studied both for general polynomial covariance type commutation relations and for important classes of polynomial covariance commutation relations associated with arbitrary monomials and affine functions. The convergence of commutators of operators in the sequences of non-commuting operators satisfying the corresponding monomial covariance commutation relation is investigated, and the sequences of such non-commuting operators converging to commuting operators, are presented.
