Abstract
If
b is a
p-block of a normal subgroup
N of a finite group
G of odd order and
b
⁎
is its Brauer correspondent in
N
N
(
Q
)
, where
Q is a defect group of
b, then for any
p-block
B of
G over
b, there exists a natural height-preserving bijection from the set of irreducible complex characters of
B lying over height-zero characters onto the set of irreducible complex characters of the Harris–Knörr correspondent
B
⁎
of
B over
b
⁎
lying over height-zero characters.
