This is an announcement for the paper "Seven views on approximate convexity and the geometry of K-spaces" by Felix Cabello Sanchez, Jesus M. F. Castillo and Pier Luigi Papini.

Abstract: As in Hokusai's series of paintings "Thirty six views of mount Fuji" in which mount Fuji's is sometimes scarcely visible, the central topic of this paper is the geometry of $K$-spaces although in some of the seven views presented $K$-spaces are not easily visible. We study the interplay between the behaviour of approximately convex (and approximately affine) functions on the unit ball of a Banach space and the geometry of Banach K-spaces.
