## Strong maximum principles for parabolic nonlinear problems with nonlocal inequalities together with arbitrary functionals.(English)Zbl 0737.35135

The paper looks for a new object for which an analogue of the maximum principle for solutions of parabolic equations is valid. The case of noncylindrical domains and nonlocal parabolic inequalities of the type $u^ i_ t(x,t)\leq f^ i(x,t,u(x,t), u^ i_ x(x,t), u^ i_{xx}(x,t);[u])\hbox { for a.e. } (x,t)$ $$i=1,\ldots,m$$; $$u=(u^ 1,\ldots,u^ m)$$, with some additional nonlocal assumptions is discussed. Here $$f^ i(\cdots;[u])$$ are functionals with respect to $$u$$.
