## Abstract:

We study the multiplicities of Deligne-Lusztig characters upon restriction from a finite reductive group to a finite reductive subgroup. The result is a qualitative formula for the growth of multiplicities in terms of complexity. For restrictions from $SO_{2n+1}$ to $SO_{2n}$ we get exact multiplicities.## References
