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 ... 
Linearization of secondorder jumpdiffusion equations
(Springer Berlin Heidelberg, 20130301)We give the exact linearization criterion for the secondorder jumpdiffusion equations. We also present several illustrative examples. 
Localized travelling waves in a prestressed thick elastic tube
(PergamonElsevier Science, 200110)In the present work, by using the exact nonlinear equations of an incompressible inviscid fluid contained in a prestressed thick elastic tube, the propagation of localized travelling wave solution in such a medium is ... 
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.
