Additionally, we establish connections between BVVI and multiobjective bilevel optimization problems (MBOP), focusing on the use of tangential subdifferentials. We investigate the relationship between the vector efficient points of MBOP and the solutions of BVVI, particularly under conditions of generalized convexity.
