On classification of finite dimensional algebras [PDF]

open access: yesarXiv, 2015
Classification and invariants, with respect to basis changes, of finite dimensional algebras are considered. An invariant open, dense (in the Zariscki topology) subset of the space of structural constants is defined. The algebras with structural constants from this set are classified and a basis to the field of invariant rational functions of ...

Verification of BSF Parallel Computational Model [PDF]

open access: yesarXiv, 2017
The article is devoted to the verification of the BSF parallel computing model. The BSF-model is an evolution of the "master-slave" model and SPMD-model. The BSF-model is oriented to iterative algorithms that are implemented in cluster computing systems. The article briefly describes the basics of the BSF-model and its cost metrics.
