## Abstract Let __E__ be a Banach space and Φ : __E__ → ℝ a 𝒞^1^‐functional. Let 𝒫 be a family of semi‐norms on __E__ which separates points and generates a (possibly non‐metrizable) topology 𝒯~𝒫~ on __E__ weaker than the norm topology. This is a special case of a gage space, that is, a topological

✦ Synopsis
The main results of this paper concern the minimax equality without algebraic structure of the underlying spaces. They include some classical minimax theorems as special cases and are independent of many other recent results of the same type. The proofs of our minimax theorems are based on some special alternative theorems established under some general connectedness conditions.

In this paper, by using particular techniques, two existence theorems of solutions for generalized quasi-variational inequalities, a minimax theorem, and a section theorem in the spaces without linear structure are established; and finally, a new coincidence theorem in locally convex spaces is obtai
