Abstract: This paper investigates several existence theorems that are central to mathematical economics and game theory, with a special emphasis on infinite-dimensional settings. By synthesizing different related formulations, including the existence of equilibria, fixed-point/coincidence theorems, surjectivity theorems, variational inequalities and Gale-Nikaido-Debreu generalizations, we aim to provide a unifying perspective across varied mathematical landscapes.
