The book "V-Invex Functions and Vector Optimization" offers a comprehensive summary and synthesis of research in the field of generalized convexity conducted over the past few decades. It focuses on V-invex functions in vector optimization, which emerged from the work of Jeyakumar and Mond in the 1990s. V-invex functions are of great interest as they enable researchers and practitioners to find better solutions for nonlinear, multi-objective, fractional, and continuous problems. These functions open up new application areas in vector optimization and expand the possibilities for solving complex problems across various disciplines. The book integrates significant research from recognized scholars and provides a well-structured, accessible, and applicable treatment for students, researchers, and practitioners in the fields of operations research, optimization, applied mathematics, and engineering.
