[S3] The category H(W) is the smallest category of Aen bimodules containing the Soergel bimodules and closed under direct sums, summands, and tensor product. This is an additive category, which has a monoidal structure via (M,N) → M⊗A N Next, we consider the (complexified) split Grothendieck group of this category,

In this chapter, we use the diagrammatic descriptions of morphisms between Bott–Samelson bimodules to give diagrammatic descriptions of two different bases for these bimodules. First, we describe the 01-basis, which is constructed by taking an iterated tensor product of a natural basis of B s. The 01-basis is depicted ...
