Kolumbán József (Kolozsvár):
Existence theorems via duality for equilibrium problems with 
trifunctions

Absztrakt:
An existence result for equilibrium problems formulated with 
trifunctions will be given. It is motivated by  variational inequalities 
governed by operators with two arguments, wich are monotone relative to 
one of them only, for example by the Navier-Stokes operator. For such a 
variational inequality the theory of equilibrium problems formulated 
with bifunctions can not be applied, however the theory of equilibrium 
problems formulated with trifunctions is suitable for it. The results 
obtained are applied to study the existence of solutions for nonlinear 
evolution equations in the setting of reflexive Banach spaces. This new 
approach leads us to improve and unify most of the recent results 
obtained in this direction.
