In this paper, we consider a nonlocal P -Laplace parabolic equation depending on the LP norm of the gradient with nonlinearity of arbitrary order. First, we prove the existence and uniqueness of weak solutions by combining the compactness and monotone methods and the weak convergence techniques in Orlicz spaces.

In this paper, we establish second-order sufficient optimality conditions for optimal control problem of 2D g-NavierStokes equations. The long-time behavior of the strong solutions was studied very recently in the autonomous case in terms of existence of a global attractor, and existence and stability of a unique stationary solution.

The Gronwall lemma and Poincaré type inequality will play a central role in our computational technique as well as of the paper. Studying the properties of solutions is important to determine the behavior of solutions over a long period of time. The obtained result particularly extends previous results for 2D NVS equations.

This paper studies the proximal point algorithm for the class of generalized P0 variational inequalities. By using the upper semicontinuity result establishing the class of weakly univalent operators, we show that the iterative sequence generated by the algorithm is bounded, approaches to the solution set of the initial problem, and each of its accumulation points is a solution to the problem, provided that the solution set is bounded.

Pectins are traditionally divided into two groups, high methoxy and low methoxy. The groupings determine the charge of the pectin and the gelation mechanism. The addition of monovalent ions changed the rheological behavior to resemble that of a strong gel whose properties depended on the type and concentration of the ions.
