From Diophantian Equations to Matrix Equations (Iv) - Diophantian Equations of Higher Degree [PDF]
Educaţia 21In the context of training and developing the skills of teachers, students and children to solve exercises and problems in Mathematics, in this paper we propose to continue the steps started in the first three papers with the same generic title and ...

Route to Chaos in a Unidirectional Ring of Three Diffusively Coupled Erbium-Doped Fiber Lasers
Photonics, 2023 We numerically investigate the dynamics of a ring consisting of three unidirectionally coupled Erbium-Doped Fiber Lasers (EDLFs) without external pump modulation.

Excitation energy of superdeformed bands in Relativistic Mean Field Theory [PDF]
, 1997 Constrained Relativistic Mean Field (RMF) calculations have been carried out to estimate excitation energies relative to the ground state for superdeformed bands in the mass regions A $\sim$ 190 and A $\sim$ 150.

Branch rings, thinned rings, tree enveloping rings [PDF]
Israel Journal of Mathematics, 2006 We develop the theory of ``branch algebras'', which are infinite-dimensional associative algebras that are isomorphic, up to taking subrings of finite codimension, to a matrix ring over themselves. The main examples come from groups acting on trees. In particular, for every field k we construct a k-algebra K which (1) is finitely generated and infinite-

Morita contexts and unitary ideals of rings [PDF]
Proceedings of the Estonian Academy of Sciences, 2021 In this paper we study Morita contexts between rings without identity. We prove that if two associative rings are connected by a Morita context with surjective mappings, then these rings have isomorphic quantales of unitary ideals.

Superdeformations in Relativistic and Non-Relativistic Mean Field Theories [PDF]
, 1999 The applications of the extensions of relativistic mean field (RMF) theory to the rotating frame, such as cranked relativistic mean field (CRMF) theory and cranked relativistic Hartree-Bogoliubov (CRHB) theory, for the description of superdeformed bands ...

Mathematical Model of Piston Ring Sealing in Combustion Engine
Polish Maritime Research, 2015 This paper presents a mathematical model of piston-rings-cylinder sealing (TPC) of a combustion engine. The developed model is an itegrated model of gas flow through gaps in TPC unit, displacements and twisting motions of piston rings in ring grooves as ...

Energy Losses Related to Ring Pack Wear in Gasoline Car Engine
Energies, 2022 Decreasing production and rising prices of cars, especially those with electric drive, lead to longer use of cars with internal combustion engines. It can be assumed that in the future, more and more cars powered by such engines with high mileage and ...

Proceedings of the American Mathematical Society, 1964 This paper presents a solution to a popular problem in the subject of rings of analytic functions. In the late 1940's it was shown that two domains Di and D2 in the complex plane were conformally equivalent (to within a certain equivalence relation) iff the rings B(Di) and B(D2) of all bounded analytic functions defined on them were algebraically ...
