Most of the natural happenings can be present by nonlinear modeling. The soliton theory is a
highly effective section of nonlinear sciences that includes soliton, multi-soliton, rational,
breather line, breather kinky, ...
Khaton, Mst. Zamilla(University of Rajshahi, Rajshahi, 2021)
In this work, we deal with the two types of variational inclusions. Firstly, we consider
the variational inclusion problem of the form
0 ∈ ζ(¯s) + g(¯s) + ξ(¯s), (A)
where S and T are Banach spaces, ζ : S → T is ...
The fundamental concept of a fuzzy set and fuzzy set operations was first introduced
by L. A. Zadeh (Zadeh, 1965) in 1965 and it provides a natural foundation for treating
mathematically the fuzzy phenomena, which exists ...
The thesis entitled "Theoretical investigations of turbulence and Magnetohydrodynamic
turbulence in incompressible fluid" is being presented for the
award of the degree of Doctor of Philosophy in Mathematics. It is the ...
We investigate the motion of spinning particles, such as Dirac fermions, in curved spacetimes by pseudo-classical mechanics models in which the spin degrees of freedom are characterized in terms of anti-commuting Grassmann ...
The thesis entitled "Analytical Investigations in Turbulent and MHD Turbulent Flow" is being presented for the award of the degree of Doctor of Philosophy in Mathematics. It is the outcome of my research conducted in the ...
This thesis studies extensively the finitely generated n-ideals of a lattice. The idea of n-ideals in a lattice was first introduced by Cornish and Noor in studying the kernels around a particular element n, of a skeletal ...
The present thesis entitled, "A Study of Characterization of Some Regular Gamma Rings " is the outcome of researches carried out by me under the close supervision of Dr. Akhil Chandra Paul, Professor, Department of ...
In Introduction we give a brief account of our work of studying spinning particles in curved spacetime of General Relativity.
In Chapter I we discuss the relevant equations for the motion of spinning particles in curved ...
The development of real time operational surge prediction system in the Bay of Bengal incorporating air bubble effects is still limited and is needed immediate attention. In this respects the study has been focused the ...
This thesis studies the nature of n-ideals of a lattice. The topic arose out of a study on the kernels, around a particular element n, of a skeletal congruence on a distributive lattice. The idea of n-ideals in a lattice ...
In this thesis we have investigated some aspects of the protoplanetary theory of planetary formation, namely, the structure of a protoplanet, sedimentation of heavy elements in a protoplanet, and the effect of mass loss ...
