Partial Menger algebras and their weakly isomorphic representation
Mathematics Open, 2022 As generalization of semigroups, Karl Menger introduced in the 1940th algebras of multiplace operations. Such algebras satisfy the superassociative law, a generalization of the associative law.

Classical solutions for a class of nonlinear wave equations [PDF]
Theoretical and Applied Mechanics, 2021 We study a class of initial value problems subject to nonlinear partial differential equations of hyperbolic type. A new topological approach is applied to prove the existence of nontrivial nonnegative solutions. More precisely, we propose a new integral

Partial Representations of Orderings [PDF]
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2018 In the present paper a new concept of representability is introduced, which can be applied to not total and also to intransitive relations (semiorders in particular). This idea tries to represent the orderings in the simplest manner, avoiding any unnecessary information.

Network Representation Learning Guided by Partial Community Structure
IEEE Access, 2020 Network Representation Learning (NRL) is an effective way to analyze large scale networks (graphs). In general, it maps network nodes, edges, subgraphs, etc. onto independent vectors in a low dimension space, thus facilitating network analysis tasks.

A Note on Numerical Representations of Nested System of Strict Partial Orders
Games, 2021 This note provides two numerical representations of a nested system of strict partial orders. The first representation is based on utility and threshold functions.

Partially complemented representations of digraphs [PDF]
Discrete Mathematics & Theoretical Computer Science, 2002 Special issue: Graph Decompositions A complementation operation on a vertex of a digraph changes all outgoing arcs into non-arcs, and outgoing non-arcs into arcs. This defines an equivalence relation where two digraphs are equivalent if one can be obtained from the other by a sequence of such operations.

European Physical Journal C: Particles and Fields, 2023 We present a lattice study of the SU(4) gauge theory with two Dirac fermions in the fundamental and two in the two-index antisymmetric representation, a model close to a theory of partial compositeness proposed by G. Ferretti.

On families of twisted power partial isometries
Karpatsʹkì Matematičnì Publìkacìï, 2022 We consider families of power partial isometries satisfying twisted commutation relations with deformation parameters $\lambda_{ij}\in\mathbb C$, $|\lambda_{ij}|=1$.

Partial Least Squares Regression for Binary Responses and Its Associated Biplot Representation
Mathematics, 2022 In this paper, we propose a generalization of Partial Least Squares Regression (PLS-R) for a matrix of several binary responses and a a set of numerical predictors. We call the method Partial Least Squares Binary Logistic Regression (PLS-BLR).

Partial representations of Hopf algebras [PDF]
Journal of Algebra, 2015 In this work, the notion of partial representation of a Hopf algebra is introduced and its relationship with partial actions of Hopf algebras is explored. Given a Hopf algebra $H$, one can associate it to a Hopf algebroid $H_{par}$ which has the universal property that each partial representation of $H$ can be factorized by an algebra morphism from $H_{
