From Geometry to Physics -- AZ: touches to the portrait
The process launched by Lobachevsky. The movement of the Kazan school of geometry towards physics. Personal memories of Alexei Zinovievich Petrov, the great Kazan geometer and theoretical physicist, who became the Author's Guiding Star. KeyWords: Alexey Zinovievich Petrov, geometry, general theory of relativity, Kazan University, Department of Relativity and Gravitation Theory, methods of teaching exact sciences.

A Parallel Transport Frame Field Approach to Soliton Surfaces associated with the Betchov-Da Rios Equation in Four Space
In the present paper, the geometric properties of a soliton surface $Ψ=Ψ(s,t)$ associated with the Betchov-Da Rios (B-DR) equation using the parallel transport frame field in four-dimensional Euclidean space are examined. We obtain the derivative formulas for the parallel transport frame field of a unit-speed $s$-parameter curve $Ψ=Ψ(s,t),$ for all $t$. We obtain the soliton surface's two basic geometric invariants, $k$ and $h,$ and some other important invariants such as Gaussian curvature…
