Commutative–non-commutative dualities [PDF]

open access: yesCanadian Journal of Physics, 2020
We show that it is in principle possible to construct dualities between commutative and non-commutative theories in a systematic way. This construction exploits a generalization of the exact renormalization group equation (ERG). We apply this to the simple case of the Landau problem and then generalize it to the free and interacting non-canonical ...

Semi-commutations and Partial commutations [PDF]

open access: yesRAIRO - Theoretical Informatics and Applications, 2000
Summary: The aim of this paper is to show that a semi-commutation function can be expressed as the compound of a sequential transformation, a partial commutation function, and the reverse transformation. Moreover, we give a necessary and sufficient condition for the image of a regular language to be computed by the compound of two sequential functions ...

Associativity as commutativity [PDF]

open access: yesJournal of Symbolic Logic, 2006
AbstractIt is shown that coherence conditions for monoidal categories concerning associativity are analogous to coherence conditions for symmetric strictly monoidal categories, where associativity arrows are identities. Mac Lane's pentagonal coherence condition for associativity is decomposed into conditions concerning commutativity, among which we ...

Writing commutators of commutators as products of cubes [PDF]

open access: yesCommunications in Algebra, 2021
It is known that commutators of commutators can be written as products of cubes, with the current upper bound on the number of cubes being 60. We discuss how proofs extracted via coset enumeration can be used to investigate this problem, and exhibit a rewriting using only 14 cubes.

Operators with commutative commutants.

open access: yesMichigan Mathematical Journal, 1988
Given operators M and N on a Hilbert space H, suppose that M (resp. N) is the direct sum of k (resp. n) copies of an operator A having a commutative commutant. Suppose further that m and k are countable cardinalities (or, any cardinalities if H is separable) and that N is a quasi-affine transform of M (i.e., \(NX=XM\) for some injective operator X with

On the Spectra of Commuting and Non Commuting Graph on Dihedral Group

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2017
Study about spectra of graph has became interesting work as well as study about commuting and non commuting graph of a group or a ring. But the study about spectra of commuting and non commuting graph of dihedral group has not been done yet.

Active commuting through natural environments is associated with better mental health: Results from the PHENOTYPE project

open access: yesEnvironment International, 2018
Background: Commuting routes with natural features could promote walking or cycling for commuting. Commuting through natural environments (NE) could have mental health benefits as exposure to NE can reduce stress and improve mental health, but there is ...

Association of changes in commute mode with body mass index and visceral adiposity: a longitudinal study

open access: yesInternational Journal of Behavioral Nutrition and Physical Activity, 2019
Background Prospective data are sparse for active commuting to work and body weight in Asia. We assessed the association of 5-year changes in commuting mode with body mass index (BMI) and the indicators of abdominal obesity in Japanese working adults ...
