. We consider an elliptic variational-hemivariational inequality P in a p -uniformly smooth Banach space. We prove that the inequality is governed by a multivalued maximal monotone operator, and, for each λ > 0, we use the resolvent of this operator to construct an auxiliary fixed point problem, denoted P λ . Next, we perform a parallel study of problems P and P λ based on their intrinsic equivalence. In this way, we prove existence, uniqueness, and well-posedness results with respect to specific Tykhonov triples. The existence of a unique common solution to problems P and P λ is proved by using the Banach contraction principle in the study of Problem P λ . In contrast, the well-posedness of the problems is obtained by using a monotonicity argument in the study of Problem P . Finally, the properties of Problem P λ allow us to deduce a convergence criterion in the study of Problem P .

. In this paper, we study a Bregman proximal point algorithm (BPPA) for convex optimization problems. Though the convergence and sublinear convergence rate for BPPA are well-understand, the linear convergence rate for BPPA has yet been thoroughly studied in the literature. In this paper, we analyze the linear convergence rate of BPPA. Under the assumption that the objective function is strongly convex relative to a Legendre function, we establish the linear convergence for the function values sequence. Moreover, if the Legendre function is strongly convex and smooth, the linear convergence for the iterative sequence of BPPA is obtained.
