Hecke algebras arise in representation theory as endomorphism algebras of induced representations. In 1979, in the simplest (equal parameter) case of such Hecke algebras, Kazhdan and Lusztig discovered a particular basis (the KL-basis) in a Hecke algebra. This book extends the theory of the KL-basis to a general class of Hecke algebras.
