Conjectures of Alperin and Brou\'e for 2-blocks with elementary abelian defect groups of order 8 Radha Kessar, Shigeo Koshitani and Markus Linckelmann Abstract. Using the classification of finite simple groups, we prove Alperin's weight conjecture and the character theoretic version of Brou\'e's abelian defect conjecture for 2-blocks of finite groups with an elementary abelian defect group of order 8.
