The monadic second-order logic of graphs XVI : Canonical graph decompositions [PDF]
Logical Methods in Computer Science, 2006 This article establishes that the split decomposition of graphs introduced by Cunnigham, is definable in Monadic Second-Order Logic.This result is actually an instance of a more general result covering canonical graph decompositions like the modular ...

Spectral Decomposition of Gramians of Continuous Linear Systems in the Form of Hadamard Products
Mathematics, 2023 New possibilities of Gramian computation, by means of canonical transformations into diagonal, controllable, and observable canonical forms, are shown. Using such a technique, the Gramian matrices can be represented as products of the Hadamard matrices ...

The Canonical Generalized Polar Decomposition [PDF]
SIAM Journal on Matrix Analysis and Applications, 2010 The polar decomposition of a square matrix has been generalized by several authors to scalar products on ℝn or ℂn given by a bilinear or sesquilinear form. Previous work has focused mainly on the case of square matrices, sometimes with the assumption of a Hermitian scalar product.

Canonical Decompositions of Affine Permutations, Affine Codes, and Split k-Schur Functions [PDF]
Electronic Journal of Combinatorics, 2012 We study the unique maximal decomposition of an arbitrary affine permutation into a product of cyclically decreasing elements, providing a new perspective on work of Thomas Lam.

Regression and Classification With Spline-Based Separable Expansions
Frontiers in Big Data, 2022 We introduce a supervised learning framework for target functions that are well approximated by a sum of (few) separable terms. The framework proposes to approximate each component function by a B-spline, resulting in an approximant where the underlying ...

Poisson-Lie T-plurality revisited. Is T-duality unique?
Journal of High Energy Physics, 2019 We investigate (non-)Abelian T-duality from the perspective of Poisson-Lie T-plurality. We show that sigma models related by duality/plurality are given not only by Manin triples obtained from decompositions of Drinfel’d double, but also by their ...

Counting Tensor Rank Decompositions
Universe, 2021 Tensor rank decomposition is a useful tool for geometric interpretation of the tensors in the canonical tensor model (CTM) of quantum gravity. In order to understand the stability of this interpretation, it is important to be able to estimate how many ...

Regular neighbourhoods and canonical decompositions for groups. [PDF]
, 2001 We find canonical decompositions for finitely presented groups which essentially specialise to the classical JSJ-decomposition when restricted to the fundamental groups of Haken manifolds.
