A functional inequality between Hessians in spaces with non-zero curvature
Tomasz Cieślak, Michał Gaczkowski, Wojciech Kryński
A version of the recent functional inequality between the Hessians of the square root and the logarithm of positive functions is proven in spaces with non-zero curvature.
Lewy curves in para-CR geometry
Wojciech Kryński, Omid Makhmali
We define a class of curves, referred to as Lewy curves, in para-CR geometry, following H. Lewy's original definition in CR geometry. We give a characterization of path geometries…
A characterization of chains in dimension three
Wojciech Kryński, Omid Makhmali
Given a 3-dimensional (para-)CR structure, its family of chains define a 3-dimensional path geometry. We provide necessary and sufficient conditions that determine whether a path g…
Deformations of dispersionless Lax systems
Wojciech Kryński
We consider dispersionless Lax systems and present a new systematic method of deriving new integrable systems from a given one. We provide examples that include: the dispersionless…
The Schwarzian derivative and Euler--Lagrange equations
Wojciech Kryński
We study the Schwarzian derivative from a variational viewpoint. Firstly we show that the Schwarzian derivative defines a first integral of the Euler--Lagrange equation of a second…
