We consider the Dirichlet problem for a class of degenerate nonlinear elliptic fourth-order equations with strengtheningly monotone principal parts, absorbing lower-order terms and L1-right-hand sides. We establish existence of solutions of the given prob... see more

In this article, we use the three critical points theorem by G. Bonanno [3] in order to investigate the multiplicity of solutions for some nonlocal degenerate problems.

In this paper we are interested in the existence of solutions for Dirichlet problem associated to the degenerate quasilinear elliptic equations 

We study an optimal control problem for degenerate elliptic variation inequality with degenerate weight function of potential type in the  so-called class of H-admissible solutions. Using an appropriate regular algorithm of perturbation, we prove att... see more

We study the behavior of solutions of parabolic equation with double nonlinearity and a degenerate absorption term. The main topic of interest is the property of finite time extinction, i.e., the solution vanish after finite time.

Context. S-blocks are one of the main transformations of many ciphers, and the search for S-boxes with improved cryptographic indicesa great deal of attention in the literature of this direction is paid. Thus, it that there are permutations (S-blocks), wh... see more
