[HTML][HTML] Trigonometric version of quantum–classical duality in integrable systems

M Beketov, A Liashyk, A Zabrodin, A Zotov - Nuclear Physics B, 2016 - Elsevier

establishes an explicit relationship between the classical N-body trigonometric Ruijsenaars …

Formal solutions to the KP hierarchy

SM Natanzon, AV Zabrodin - Journal of Physics A: Mathematical …, 2016 - iopscience.iop.org
We find all formal solutions to the ℏ-dependent KP hierarchy. They are characterized by
certain Cauchy-like data. The solutions are found in the form of formal series for the tau …
