Tangent bundle geometry induced by second order partial differential equations
D. J. Saunders, O. Rossi, G. E. Prince
We show how the tangent bundle decomposition generated by a system of ordinary differential equations may be generalized to the case of a system of second order PDEs `of connection…
On entropy of dynamical systems with almost specification
Dominik Kwietniak, Piotr Oprocha, Michał Rams
We construct a family of shift spaces with almost specification and multiple measures of maximal entropy. This answers a question from Climenhaga and Thompson [Israel J. Math. 192…
Deformations of current Lie algebras. I. Small algebras in characteristic 2
Alexander Grishkov, Pasha Zusmanovich
We compute low-degree cohomology of current Lie algebras extended over the 3-dimensional simple algebra, compute deformations of related semisimple Lie algebras, and apply these re…
On the last question of Stefan Banach
Pasha Zusmanovich
We discuss the last question of Banach, posed by him in 1944, shortly before his death, about extension of a ternary map to superposition of a binary map. We try to put things into…
