Zagreb indices of commuting and non-commuting graphs of finite groups and Hansen-Vukičević conjecture [PDF]
arXiv, 2023 In this paper we compute first and second Zagreb indices of commuting and non-commuting graphs of finite groups and determine several classes of finite groups such that their commuting and non-commuting graphs satisfy Hansen-Vuki\v{c}evi\'c conjecture.

Commutators and Squares in Free Nilpotent Groups
International Journal of Mathematics and Mathematical Sciences, 2009 In a free group no nontrivial commutator is a square. And in the free group F2=F(x1,x2) freely generated by x1,x2 the commutator [x1,x2] is never the product of two squares in F2, although it is always the product of three squares.

, 2009 The ternary commutator or ternutator, defined as the alternating sum of the product of three operators, has recently drawn much attention as an interesting structure generalising the commutator.

Advanced Science, EarlyView.How locus coeruleus noradrenergic‐spinal projections and subsequent α2A adrenoceptors‐CaMKII signaling cascades contribute to electroacupuncture‐induced antinociception in postoperative pain in mice is described. Abstract Postoperative pain remains a significant challenge in healthcare.

Isometric endomorphisms of free groups [PDF]
, 2011 An arbitrary homomorphism between groups is nonincreasing for stable commutator length, and there are infinitely many (injective) homomorphisms between free groups which strictly decrease the stable commutator length of some elements. However, we show in

Fluctuation, dissipation, and thermalization in non-equilibrium AdS_5 black hole geometries
, 2011 We give a simple recipe for computing dissipation and fluctuations (commutator and anti-commutator correlation functions) for non-equilibrium black hole geometries.

Proceedings of the Fifth Israeli Symposium on Theory of Computing and Systems, 2001 AbstractWe consider polynomial-time Turing machines that have access to two oracles and investigate when the order of oracle queries is significant. The oracles used here are complete languages for the Polynomial Hierarchy (PH). We prove that, for solving decision problems, the order of oracle queries does not matter.

Amphibious Generator via Mechanical Coupling for Versatile Energy Harvesting
Advanced Energy and Sustainability Research, EarlyView.An amphibious hybrid triboelectric nanogenerator–electromagnetic generator (TENG–EMG) efficiently harvests energy from wind and water. By integrating TENG and EMG units with a gear‐assisted mechanism, it enhances power output and powers small electronic devices.

Weighted commutators in semi-abelian categories [PDF]
Journal of Algebra, 397, 643-665, 2014, 2015 We introduce new notions of weighted centrality and weighted commutators corresponding to each other in the same way as centrality of congruences and commutators do in the Smith commutator theory. Both the Huq commutator of subobjects and Pedicchio's categorical generalization of Smith commutator are special cases of our weighted commutators; in fact ...
