    In this chapter we shall consider l-modular represenations of finite general linear groups in non-defining characteristic l > 0. We focus the nicest l-block algebras in this representation theory, which are also known as unipotent Rouquier blocks.
    Let B(w,rho) be the unipotent l-block algebra of a general linear group over the finite field with q elements associated with an e-weight w > 0 and a Rouquier e-core rho with respect to w where e is the multiplicative order of q modulo l > 0. (See the second paragraph of Sect. A for the definition of rho.)
    We assume that B(w,p) has an abelian defect, ie, l > w. It is known that there exists a Morita equivalence F between B(w,rho) and the wreath product block B1,(sic). This result is obtained by W. Turner and the second author independently. The both methods are completely identical each other and are very similar to J. Chuang and R. Kessar's method on symmetric groups.
    R. Kessar's method on symmetric groups.
    In this chapter, under the equivalence F we shall determine the explicit correspondences of the simple, the Young and the Specht modules over the Rouquier block B(w,p) and the local subgroup block B(sic). The result is used to prove the intial condition of runner removal Morita equivalence theorem.

    In representation theory of finite groups, there is a well-known and important conjecture due to M. Broue. He has conjectured that, for any prime p, if a finite group G has an abelian Sylow p-subgroup P, then the principal p-blocks of G and the normalizer N(G)(P) of P in G are derived equivalent. Let q be a power of a prime such that q = 2 or 5 (mod 9), In this paper we show that Broue's conjecture is true for p = 3 and for G = PSL(4)(q) and G = PSL(5)(q). In these cases, G has elementary abelian Sylow 3-subgroups of order 9. What we prove here is the following. In the case G = PSL(4)(q) all the principal 3-blocks of G are Morita (even Puig) equivalent independently of infinitely many q. In the case G = PSL(5)(q) all the principal 3-blocks of G are Morita (even Puig) equivalent to the principal 3-block of N(G)(P) independently of infinitely many q. (C) 2000 Academic Press.
