Motiur Rahman,Noriatsu Matsui,Yukio IkemotoWe review the theory of Toeplitz extensions and their role in operator .-theory, including Kasparov’s bivariant .-theory. We then discuss the recent applications of Toeplitz algebras in the study of solid-state systems, focusing in particular on the bulk-edge correspondence for topological insulators.

Comments on Mechanisms of Release,In this paper we study one-point rank one commutative rings of difference operators. We find conditions on spectral data which specify such operators with periodic coefficients.

Dynamics of Rotors and FoundationsWe report on the trigonometric spin Ruijsenaars–Sutherland hierarchy derived recently by Poisson reduction of a bi-Hamiltonian hierarchy associated with free geodesic motion on the Lie group U(.). In particular, we give a direct proof of a previously stated result about the form of the second Poisson bracket in terms of convenient variables.

Dynamics of Science-Based InnovationWe describe sufficient maximality conditions for the classes of graph surfaces on two-step Carnot groups with sub-Lorentzian structure. In particular, we introduce a non-holonomic notion of variation of the area functional.

https://doi.org/10.1007/978-3-540-88831-4We consider certain degenerations of trigonal curves and hyperelliptic curves, which we call one step degeneration. We compute the limits of corresponding quasi-periodic solutions using the Sato Grassmannian. The mixing of solitons and quasi-periodic solutions is clearly visible in the obtained solutions.
