We compare the solution of the generalized Boussinesq systems, for various values of a,b,c,d${a,b,c,d}$ , η t +u x +ε((ηu) x +au xxx -bη xxt )=0$\eta _t +u_x +\varepsilon ((\eta u)_x +au_{xxx} -b\eta _{xxt}) = 0$ , u t +η x +ε(uu x +cη xxx -du xxt )=0$u_t +\eta _x +\varepsilon (uu_x +c\eta _{xxx} -du_{xxt}) = 0$ . These systems describe the two-way...

We continue the description of the C*-algebras of low-dimensional nilpotent Lie groups as algebras of operator fields defined over their spectra. We show here that the C*-algebras of the three 6-dimensional nilpotent Lie groups having the group G5,2 as quotient group modulo the centre have norm controlled dual limits.

In this paper, we derive new integral inequalities for functions with h -convex and h-concave first derivatives. As a consequence, we give new estimates for the remainder term of the midpoint, trapezoid, and Simpson formulae for functions whose derivatives in absolute value at certain power are h-convex and h -concave and we point out the results f...

The notion of periodic unfolding has become a standard tool in the theory of periodic homogenization. However, all the results obtained so far are only applicable to the “flat” Euclidean space ℝ n ${\mathbb {R}^n}$ . In this paper, we present a generalization of the method of periodic unfolding applicable to structures defined on certain compact Ri...

A general framework for a relaxed proximal point algorithm using the notion of A-maximal accretive is developed. Convergence analysis for this algorithm in the context of solving a class of inclusion problems is explored along with some results on the resolvent operator corresponding to A-maximal accretive mappings.

In this paper, we propose a one-step iteration for the approximation of common fixed points of two uniformly continuous total asymptotically quasi-nonexpansive mappings in uniformly convex hyperbolic spaces. We establish strong convergence and Δ-convergence results of the proposed iteration in this setting. As a consequence, our convergence results...

In the present paper, we have studied quantum dynamical systems of difference posets, their equivalence, subsystems and spectra. It is shown that every subsystem of a mixing quantum dynamical system is mixing, and also a bounded spectrum of quantum dynamical systems has its supremum, and all such suprema are equivalent. Entropy of subsystems of a q...
