Xiaolong Lou,Xinyi Li,Yuhaozhe Zheng,Yan ShiThis is an expository paper describing a few selected topics of Ilya Spitkovsky’s work. We focus the attention on his pioneering contributions to the detection and identification of massive local spectra of Toeplitz operators caused by jumps of the symbols and embark on the subsequent development of the story.

Hiroyuki Ohshima,Shigenobu ShimadaAn inversion formula for Hankel- and Toeplitz-Bezoutians has been previously established using results on resultant matrices as well as the kernel structure of Hankel and Toeplitz matrices. Here we establish a direct, short and quite natural proof of this inversion formula (exemplified in the Hankel case) avoiding any detours.
