Abstract

We study the 0-Hecke algebra of an arbitrary finite Coxeter group, building on work of Norton (J. Austral. Math. Soc. Ser. A 27 (1979) 337). We examine the correspondence between injective and projective modules, extensions between simple modules and (in type A) the structure of induced simple modules.
