Recently, a strong exponential character bound was established in [Acta Math. 221 (2018), pp. 1–57] for all elementsof a finite reductive groupwhich satisfy the condition that the centralizeris contained in a-split Levi subgroupofand thatis defined over a field of good characteristic. In this paper, assuming a weak version of Lusztig’s conjecture relating irreducible characters and characteristic functions of character sheaves holds, we considerably generalize this result by removing the condition thatis split. This assumption is known to hold wheneveris connected or whenis a special linear or symplectic group andis defined over a sufficiently large finite field. References
