On the structure of the automorphism group of a compact Klein surface with N boundary components (1\(\leq N\leq 4)\)
Let X be a compact Klein surface, that is, X is a compact surface with or without boundary together with an equivalence class of dianalytic atlases on X. In this paper we establish that if X is a compact Klein surface with N boundary components (1\(\leq N\leq 4)\) of algebraic genus \(p\geq 2\), and H is the automorphisms group of X, then H is soluble.
