Equivalence classes in the Weyl groups of type Bn

- We consider two families of equivalence classes in the Weyl groups of type B n which are suggested by the study of left cells in unequal parameter Iwahori-Hecke algebras. Both families are indexed by a non-negative integer r. It has been shown that the first family coincides with left cells corresponding to the equal parameter Iwahori-Hecke algebra when r=0; the equivalence classes in the second family agree with left cells corresponding to a special class of choices of unequal parameters when r is sufficiently large. Our main result shows that the two families of equivalence classes coincide, suggesting the structure of left cells for remaining choices of the Iwahori-Hecke algebra parameters. © 2007 Springer Science+Business Media, LLC.
Bilad al-brazil: The importance of west african scholars in brazilian islamic education and practice in historic and contemporary perspective

- While it is well established now that the middle passage did not entirely separate Africans who were forcibly brought to the Americas from their home cultures and traditions, these connections are often studied and understood in the form of survivals or ancestral memory. This paper argues that in major urban centers in Brazil until around the time of World War I, West Africans not only managed to recreate Islamic communities and intellectual traditions, but maintained important contacts with their homelands. In much the same way that scholars have argued that the Sahara constituted an avenue of exchange and connection between North Africa and Bilad al-Sudan, I argue here that the Atlantic Ocean was not an insurmountable barrier but provided opportunities for African Muslims to extend the traditions of Bilad al-Sudan into Brazil—albeit to a much lesser extent.
