The discussion centers on recommendations for books and preprints related to the study of Banach manifolds and differential geometry (DG) in a broader context. Participants suggest "The Convenient Setting for Global Analysis," which focuses on infinite-dimensional manifolds, as a valuable resource. There is a consensus on the need for textbooks that cover more general geometric objects beyond standard courses in differential geometry, with Banach manifolds being a key area of interest. Additional recommendations include Lang's "Fundamentals of Differential Geometry" and Abraham, Marsden, and Ratiu's "Manifolds, Tensor Analysis and Applications," which are noted for their comprehensive treatment of the subject. The conversation reflects a quest for deeper understanding and resources in advanced geometric studies.
