New Vector-Space Embeddings for Recommender Systems
Applied Sciences, 2021 In this work, we propose a novel recommender system model based on a technology commonly used in natural language processing called word vector embedding.

Vector space partitions of $\operatorname{GF}(2)^8$ [PDF]
arXiv, 2023 A vector space partition $\mathcal{P}$ of the projective space $\operatorname{PG}(v-1,q)$ is a set of subspaces in $\operatorname{PG}(v-1,q)$ which partitions the set of points. We say that a vector space partition $\mathcal{P}$ has type $(v-1)^{m_{v-1}} \dots 2^{m_2}1^{m_1}$ if precisely $m_i$ of its elements have dimension $i$, where $1\le i\le v-1$.

Partitions of vector spaces [PDF]
Proceedings of the American Mathematical Society, 1990 The following question is answered: If the real line is partitioned into countable sets, is there a Hamel basis that picks at most one element from each member of the partition?

Asymmetrical Six-Phase Space Vector Pwm Scheme
Mokslas: Lietuvos Ateitis, 2014 Multiphase electric motors have smaller torque pulsations and are more reliable that their three-phase alternatives. However, standard electricity grids around the world are three-phase, so power inverter is needed to drive multiphase motors. Inverter is

arXiv, 2005 A Smarandache multi-space is a union of $n$ spaces $A_1,A_2,..., A_n$ with some additional conditions holding. Combining Smarandache multi-spaces with linear vector spaces in classical linear algebra, the conception of multi-vector spaces is introduced. Some characteristics of a multi-vector space are obtained in this paper.

Proceedings of the American Mathematical Society, 1952 Simple consequences of these assumptions are: x>y implies x+z >y+z;x>y implies Xx>Xy for real positive scalarsX; x > 0 if and only if 0>-x. An important class of examples of such V's is due to R. Thrall ; we shall call these spaces lexicographic function spaces (LFS), defining them as follows: Let T be any simply ordered set ; let / be any real-valued ...

Categories of vector spaces and Grassmannians [PDF]
arXiv, 2017 We construct a new category of vector spaces which contains both the standard category of vector spaces and Grassmannians. Its space of objects classifies vector bundles, its space of morphisms classifies bundle isomorphisms, and it can be delooped to obtain the topological $K$-theory spectrum.

Vectorial Formalism of Polyphase Synchronous Machine With Permanents Magnets
Aceh International Journal of Science and Technology, 2013 This paper presents a mathematical model that transforms the real machine to fictitious machines and our goal is to simulate these and see the behavior of these machines in load.

The subspace structure of finite dimensional Beidleman near-vector spaces [PDF]
arXiv, 2018 The subspace structure of Beidleman near-vector spaces is investigated. We characterise finite dimensional Beidleman near-vector spaces and we classify the R-subgroups of finite dimensional Beidleman near-vector spaces. We provide an algorithm to compute the smallest R-subgroup containing a given set of vectors.

The $oτ$-continuous, Lebesgue, KB, and Levi operators between vector lattices and topological vector spaces [PDF]
arXiv, 2021 We investigate the $o\tau$-continuous/bounded/compact and Lebesgue operators from vector lattices to topological vector spaces; the KB operators between locally solid lattices and topological vector spaces; and the Levi operators from locally solid lattices to vector lattices.
