Eigenvalue Problems For An Elliptic Equation With Two Singular Coefficients, Asror M. Shokirov
Eigenvalue Problems For An Elliptic Equation With Two Singular Coefficients, Asror M. Shokirov
Scientific Bulletin. Physical and Mathematical Research
For the elliptic type of differential equation with two singular coefficients, the quadratic values of the Dirixle and Dirixle-Neumann problems were found in the quarter in that work. The field and boundary conditions for solving these problems are described in the polar coordinate system. The result is a rectangle in the polar coordinate system. Then, we used the method of separating variables in the right rectangle, that is, divided the variables by the equation and divided the problem into two distinct values for ordinary differential equations. The first of the ordinary differential equations is the substitution of , where the …
The Task Of Prosecuting Simple Differential Games On The Rectangle, Azizhon O. Zunnunov
The Task Of Prosecuting Simple Differential Games On The Rectangle, Azizhon O. Zunnunov
Scientific Bulletin. Physical and Mathematical Research
The theory of differential games is developed and resulted from modeling technical problems. Some of the problems in differential games theory can be described as controlling two moving objects, i.e. one of them is the follower that tries to catch the other object, and obviously the other object is the runner. The runner tries to run away from the follower. Most of the practical and theoretical IT problems, planning, technical and other challenges will be derived to the differential games theory for resolution. Thus researching this theory is one of most important topics currently. A lot of researchers contributed enormous …
Description Of 2-Local Two Sided Multiplication On An Algebra Of Matrices, Farhodjon N. Arzikulov, Kamola A. Solijanova
Description Of 2-Local Two Sided Multiplication On An Algebra Of Matrices, Farhodjon N. Arzikulov, Kamola A. Solijanova
Scientific Bulletin. Physical and Mathematical Research
The present paper is devoted to 2-local derivation on associative and Jordan matrix rings. In 1997, P. Semrl introduced the notion of 2-local derivations and described 2-local derivations on the algebra ¬B(H) of all bounded linear operators on the infinite-dimensional separable Hilbert space H. A similar description for the finite-dimensional case appeared later in 2004. In the paper Y. Lin and T. Wong 2-local derivations have been described on matrix algebras over finite dimensional division rings. In 2012 Sh. Ayupov, K. Kudaybergenov suggested a new technique and have generalized the above mentioned results for abritrary Hilbert spaces. Namely they considered …

Differential Games Of The Second Order, B. T. Samatov Doctor Of Physics-Mathematics, Professor, U. B. Soyibboev Master Student, U. A. Mirzamahmudov Master Student
Scientific journal of the Fergana State University
In this paper, we study the pursuit-evasion problem for the second order differential game when the initial positions of moving objects are linearly dependent and controls of the players have geometric constraints. The new sufficient solvability conditions are obtained for problems of the pursuit and evasion.

An Analysis Of The Work Of Passengers Trains On Twozone Sections And Their Alert Automation, N. S. Tokhirov
An Analysis Of The Work Of Passengers Trains On Twozone Sections And Their Alert Automation, N. S. Tokhirov
Central Asian Problems of Modern Science and Education
Company "Uzbekistan railways" has made a great contribution to the safety of passenger traffic. It is expected that passenger trains will have a number of factors affecting the large passenger traffic in the coming days and will be in the future. That is why passenger trains require that the issuance of warnings from workers of the running facilities, electricity, signaling and communications, as well as station attendants at the station by dispatchers, be accurate and error free. This article describes the automation of issuing warnings for trains and trains at two zones
