On compactness of commutators of convolution type operators with PQC data

Applying the theory of Calderón- Zygmund operators, we study the compactness of commutators of multiplication operators $aI$ and convolution operators $W^0(b)$ on weighted Lebesgue spaces with Muckenhoupt weights on the real line for some clases of piecewise quasicontinuous functions $a,b$. Applications of these results are considered. The talk is based on a joint work with Isaac De la Cruz Rodríguez and Iván Loreto Hernández.
