We study transfer operators
associated to a
finite family {ψω} of
(r ≥ 1)
transversal maps Uω →
, where
Uω ⊂
, with
compactly
supported weights gω, acting on k-forms in
. Using the definitions of sharp
trace Tr≯
and flat trace Tr≭, the following formula holds between
power series:
. Following ideas of
Kitaev [17], we define kneading operators
(z), which are kernel operators. Our main result is
the equality (as formal power series)
We also show that a finite power of
(z) is
trace-class on L2. This (partially) generalizes results
obtained by Baladi, Kitaev, Ruelle, and Semmes in dimension one,
complex and real [8], [10]).
