Multiresolution kernel matrix algebra [PDF]
Numerische Mathematik, 2022 We propose a sparse algebra for samplet compressed kernel matrices to enable efficient scattered data analysis. We show that the compression of kernel matrices by means of samplets produces optimally sparse matrices in a certain S-format. The compression

A Study on Neutrosophic Algebra [PDF]
Neutrosophic Sets and Systems, 2022 The notion of neutrosophic algebra, ideal of neutrosophic algebra, kernel and neutrosophic quotient algebra have been proposed in this paper. We characterize some properties of neutrosophic algebra and proved that every quotient neutrosophic algebra is ...

Determinantal Point Processes in Randomized Numerical Linear Algebra [PDF]
Notices of the American Mathematical Society, 2020 Randomized Numerical Linear Algebra (RandNLA) uses randomness to develop improved algorithms for matrix problems that arise in scientific computing, data science, machine learning, etc. Determinantal Point Processes (DPPs), a seemingly unrelated topic in

Some monounary algebras with EKP [PDF]
Mathematica Bohemica, 2020 An algebra $\cal A$ is said to have the endomorphism kernel property (EKP) if every congruence on $\cal A$ is the kernel of some endomorphism of $\cal A$. Three classes of monounary algebras are dealt with.

A Lie Bracket for the Momentum Kernel [PDF]
Communications in Mathematical Physics, 2020 We prove results for the study of the double copy and tree-level colour/kinematics duality for tree-level scattering amplitudes using the properties of Lie polynomials.

LaraDB: A Minimalist Kernel for Linear and Relational Algebra Computation [PDF]
BeyondMR@SIGMOD, 2017 Analytics tasks manipulate structured data with variants of relational algebra (RA) and quantitative data with variants of linear algebra (LA). The two computational models have overlapping expressiveness, motivating a common programming model that ...

L-Fuzzy Congruences and L-Fuzzy Kernel Ideals in Ockham Algebras
Journal of Mathematics, 2021 In this paper, we study fuzzy congruence relations and kernel fuzzy ideals of an Ockham algebra A,f, whose truth values are in a complete lattice satisfying the infinite meet distributive law.
