Simultaneous Measurements of Noncommuting Observables: Positive Transformations and Instrumental Lie Groups [PDF]

Entropy, 2023
We formulate a general program for describing and analyzing continuous, differential weak, simultaneous measurements of noncommuting observables, which focuses on describing the measuring instrument autonomously, without states.

On 4-dimensional Einsteinian manifolds with parallel null distribution [PDF]

ریاضی و جامعه, 2023
In this paper, we investigate the Einsteinian manifolds with parallel null distribution. For this purpose, we first obtain the equations, which are known as Einstein's equations, that lead to finding the mentioned manifolds and then, we reduce Einstein's

Quantum groups and Yang-Baxter equations

Natural Science Review
This introductory  review is devoted to the newest section of the theory of symmetries -- the theory of quantum groups. The principles of the theory of quantum groups are reviewed from the point of view of the possibility of their use for deformations ...

Metoda Wyznaczania Pewnych Klas Przepływów za Pomocą Modelowania na Grupach Liego

Engineering Transactions, 1963
The method described concerns a class of geometrically simple flows. It is based on an analysis of the geometrical structure of the equations considered and the research of Lie transformation groups discerned by this structure.
