This book gives a complete description of the de Rham complex of the Drinfeld space of dimension n − 1 as a complex of representations of GL n ( K ), where n ≥ 2 and K is a finite field extension of the field of p -adic numbers. The group GL n ( K ) acts on the Drinfeld space of dimension n − 1, hence on its complex of differential forms, yielding representations of GL n ( K ) that mathematicians began to study in the 1980s. Understanding these representations was one of the main motivations for the development of the theory of locally analytic representations of GL n ( K ), which can be seen as a p -adic analogue of Harish-Chandra&s (gl n , K )-modules (in the latter, K is a maximal compact subgroup of GL n (R)). A transparent description is provided of the global sections of the de Rham complex of the Drinfeld space of dimension n -1 as a complex of (duals of) locally analytic representations of GL n ( K ), and an explicit partial splitting of this complex is constructed in the derived category of (duals of) locally analytic representations of GL n ( K ). Multiple intermediate results on Ext groups of locally analytic representations are established, which may be useful in other contexts. Requiring a light background in locally analytic representations, modules over enveloping algebras, and rigid spaces, the book is aimed at a general audience of number theorists and representation theorists.
