Geometric characteristics of quantum evolution: curvature and torsion
We study characteristics of quantum evolution which can be called curvature and torsion. The curvature shows a deviation of the state vector in quantum evolution from the geodesic line. The torsion shows a deviation of state vector from the plane of evolution (a two-dimensional subspace) at a give...

a deviation of the state vector in quantum evolution from the geodesic line. The torsion shows a deviation of
state vector from the plane of evolution (a two-dimensional subspace) at a given time.
Ми вивчаємо характеристики квантової еволюцiї, такi як кривизна та кручення. Кривизна показує вiдхилення вектора стану пiд час квантової еволюцiї вiд геодезичної лiнiї. Кручення визначає вiдхилення
вектора стану вiд площини еволюцiї (двовимiрний пiдпростiр) в заданий момент часу.
