Abstract: A new class of bilevel generalized mixed equilibrium problems(BGMEP)involving generalized mixed variational-like inequality problems was introduced and studied in reflexive Banach spaces. First,an auxiliary generalized mixed equilibrium problem(AGMEP)to compute the approximate solutions of the bilevel generalized mixed equilibrium problems involving generalized mixed variational-like inequality problems was introduced.By using a minimax inequality,the existence and uniqueness of solutions of the AGMEP was proved under quite mild conditions without any coercive assumptions.By using auxiliary principle technique,new iterative algorithm to compute the approximate solutions of the BGMEP were suggested and analyzed.The strong convergence of the iterative sequences generated by the algorithms was proved under quite mild conditions without any coercive assumptions.These results are new and generalize some recent results in this field. -
