Analytical approximate solutions for nonplanar Burgers equations by weighted residual method
(Elsevier B.V., 2020-08-13)In this work, analytical approximate progressive wave solutions for the generalized form of the nonplanar KdV-Burgers (KdV-B) and mKdV-Burgers (mKdV-B) equations are presented and the results are discussed. Motivated with ... -
On the Hochschild homology of smash biproducts
(Elsevier B.V., 2021-02)We develop a new spectral sequence in order to calculate the Hochschild homology of smash biproducts (also called the twisted tensor products) of unital associative algebras A#B provided one of A or B has Hochschild dimension ... -
A note on the cylindrical waves with transverse distortion in a plasma with vortex electron distribution

Analysis of periodic and solitary waves in a magnetosonic quantum dusty plasma
(Springer, 2021-06)The propagation of nonlinear magnetosonic waves in electron–ion–dust (complex) plasmas has been studied by considering the effects of Bohm potential in the presence of an external magnetic field. By using the quantum ... -
Matched pairs of m-invertible 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 m-inverse property loops. The theory is upgraded to the Hopf level, and the m-invertible Hopf quasigroups are introduced. -
