On 3 October at 18:00 p.m. (Moscow time)

Speakers:

  • Evgeny Galakhov, Professor, Doctor of Physical and Mathematical Sciences;
  • Vase Esmelalem Admasu, PhD student, RUDN University.

Sufficient conditions for the absence of nontrivial weak solutions of nonlinear inequalities and systems with integer powers of the Laplace operator and with a nonlinear term of the form a(x)|∇(∆mu)|q+ b(x)|∇u|s are considered. At the same time, optimal a priori estimates obtained by the nonlinear capacity method with an appropriate choice of trial functions are used. As a result, the absence of nontrivial weak solutions of nonlinear inequalities and systems is proved to the contrary.
