Lagrangian dynamics on matched pairs
(Elsevier Science BV, 201701)Given a matched pair of Lie groups, we show that the tangent bundle of the matched pair group is isomorphic to the matched pair of the tangent groups. We thus obtain the Euler–Lagrange equations on the trivialized matched ... 
Largest eigenvalues of the discrete pLaplacian of trees with degree sequences
(Int Linear Algebra Soc, 200903)Trees that have greatest maximum pLaplacian eigenvalue among all trees with a given degree sequence are characterized. It is shown that such extremal trees can be obtained by breadthfirst search where the vertex degrees ... 
Lie cebiroidleri üzerindeki Lagrange dinamiğinin eşlenmesi problemi üzerine
(Süleyman Demirel Üniversitesi, 20210815)Lie cebiroidleri, bir anlamda tanjant demetini ve Lie cebiri yapısını beraber ihtiva eden ve fakat daha genel olan geometrik inşaalardır. Lagrange dinamiğinin en genel ifadesi Lie cebiroidleri üzerinde mümkündür. Bu makalede, ... 
Linearization of secondorder jumpdiffusion equations

Matched pair analysis of the Vlasov plasma
(American Institute of Mathematical SciencesAIMS, 202106)We present the Hamiltonian (LiePoisson) analysis of the Vlasov plasma, and the dynamics of its kinetic moments, from the matched pair decomposition point of view. We express these (LiePoisson) systems as couplings of ... 
Matched pairs of minvertible hopf quasigroups
(Institute of Mathematics, Academy of Sciences Moldova, 2020)The matched pair theory (of groups) is studied for a class of quasigroups; namely, the minverse property loops. The theory is upgraded to the Hopf level, and the minvertible Hopf quasigroups are introduced. 
A method for higherorder expansion in nonlinear ionacoustic waves
(PergamonElsevier Science, 200003)The basic equations describing the nonlinear ionacoustic waves in a cold collisionless plasma, in the longwave limit, is reexamined through the use of a modified multiplescale expansion method. Expanding the field ...
