Golod-Shafarevich algebras, free subalgebras and Noetherian images [PDF]

open access: yes, 2012
It is shown that Golod–Shafarevich algebras of a reduced number of defining relations contain noncommutative free subalgebras in two generators, and that these algebras can be homomorphically mapped onto prime, Noetherian algebras with linear growth.

Linear maps on real C* - algebras and related structures [PDF]

open access: yes, 2010
PhDIn this thesis we obtain new results on the structures of real C*-algebras and nonsurjective isometries between them. Some of the results have been published in [1].

Properties and examples of FCR-algebras [PDF]

open access: yes, 2001
An algebra A over a field k is FCR if every finite dimensional representation of A is completely reducible and the intersection of the kernels of these representations is zero.

Invariants of automorphic lie algebras [PDF]

open access: yes
Automorphic Lie Algebras arise in the context of reduction groups introduced in the late 1970s [35] in the field of integrable systems. They are subalgebras of Lie algebras over a ring of rational functions, denied by invariance under the action of a ...

Smarandache BE-Algebras [PDF]

open access: yes, 2013
A study of the notions of Smarandache n-structure CI-algebras and Smarandache weak BE-algebras. Smarandache algebraic structures have been studied in a series of eleven books by W. B.

Sharply Orthocomplete Effect Algebras

open access: yesActa Polytechnica, 2010
Special types of effect algebras E called sharply dominating and S-dominating were introduced by S. Gudder in [7, 8]. We prove statements about connections between sharp orthocompleteness, sharp dominancy and completeness of E.

Automorphic Lie algebras with dihedral symmetry [PDF]

open access: yes, 2014
The concept of automorphic Lie algebras arises in the context of reduction groups introduced in the early 1980s in the field of integrable systems.

More on PT-Symmetry in (Generalized) Effect Algebras and Partial Groups

open access: yesActa Polytechnica, 2011
We continue in the direction of our paper on PT-Symmetry in (Generalized) Effect Algebras and Partial Groups. Namely we extend our considerations to the setting of weakly ordered partial groups.

D-Posets with Meet Function

open access: yesAdvances in Electrical and Electronic Engineering, 2004
For any two observables on a full tribe we can always construct a two–dimensional observable. In this case the crucial role is played by pointwise multiplication of the functions of tribe.

Quiver subtractions

open access: yesJournal of High Energy Physics, 2018
We study the vacuum structure of gauge theories with eight supercharges. It has been recently discovered that in the Higgs branch of 5d and 6d SQCD theories with eight supercharges, the new massless states, arising when the gauge coupling is taken to ...
