Equations in partial algebras [PDF]

, 1970
In the theory of equational classes of algebras as developed by G. Birkhoff one considers classes of complete algebras only. In partial algebras one can define several non-equivalent notions of validity of equations...Mathematics, Department ...

Mapping the Innovation DNA of Agribusiness Firms: A Multi‐Method Analysis of Strategic Capabilities and Performance

Agribusiness, EarlyView.
ABSTRACT Innovation is essential for competitiveness in agribusiness facing dynamic environments. This study examines how market orientation, marketing, relational, and social capabilities influence innovation performance. Using data from 751 Spanish firms and a multi‐method approach that integrates Structural Equation Modeling (PLS‐SEM), Necessary ...

Partial Constant Hesitant Fuzzy Sets on UP-Algebras

Journal of New Theory, 2018
In this paper, partial constant hesitant fuzzy sets on UP-algebras are introduced and proved some results. Further, we discuss the relation between partial constant hesitant fuzzy sets and UP-subalgebras (resp.

An asymptotic expansion of the solution of a semi-linear partial differential equation implied by a nonlinear Feynman–Kac formula

International Journal of Mathematics for Industry
This paper introduces an asymptotic expansion for the smooth solution of a semi-linear partial differential equation. Our scheme is based on Itô’s formula, Taylor’s expansion, nonlinear Feynman–Kac formula and some algebras.

Higgs and Coulomb branches from vertex operator algebras

Journal of High Energy Physics, 2019
We formulate a conjectural relation between the category of line defects in topologically twisted 3d N $$ \mathcal{N} $$ = 4 supersymmetric quantum field theories and categories of modules for Vertex Operator Algebras of boundary local operators for the ...

The Algebra of Partial Equivalence Relations [PDF]

Electronic Notes in Theoretical Computer Science, 2016
AbstractRecent work by the author with Bonchi and Sobociński shows how PROPs of linear relations (subspaces) can be presented by generators and equations via a “cube construction”, based on letting very simple structures interact according to PROP operations of sum, fibered sum and composition via a distributive law.

Collapsing partial combinatory algebras [PDF]

, 1996
Partial combinatory algebras occur regularly in the literature as a framework for an abstract formulation of computation theory or recursion theory. In this paper we develop some general theory concerning homomorphic images (or collapses) of pca''s, obtained by identification of elements in a pca.

From continuous to interruptible distillation: Flexible electric heating column architecture with fast start‐up

AIChE Journal, EarlyView.
Abstract Electrification of distillation offers a promising route to reducing scope‐1 emissions from one of the chemical industry's most energy‐intensive unit operations. However, conventional adiabatic columns are dynamically inflexible: Long, energy‐intensive start‐ups make shutdown and restart impractical under variable electricity prices and ...

Dictionary‐based weak‐form training for noise‐robust series hybrid models with multiplicative unknowns

AIChE Journal, EarlyView.
ABSTRACT Hybrid modeling combines first‐principles equations with a data‐driven subcomponent. Training for the data‐driven part is sensitive to measurement noise when training targets are constructed using pointwise time derivatives. Beyond differentiation errors, hybrid models involve solving an inverse problem to estimate the data‐driven term, which ...

Partial *-Algebras Of Closable Operators: A Review [PDF]

, 1995
This paper reviews the theory of partial *-algebras of closable operators in Hilbert space (partial O*-algebras ), with some emphasis on partial GW*-algebras. First we discuss the general properties and the various types of partial *-algebras and partial
