  On the basis of an unified theoretical formulation of resonances and
resonance states in the rigged Hilbert spaces the spectral analysis of the
Frobenius-Perron operators corresponding to the exactly solvable chaotic map
has been developed. Tent map as the simplest representative of exactly solvable
chaos have been studied in details in frames of the developed approach. An
extension the Frobenius-Perron operator resolvent to a suitable rigged Hilbert
space has been constructed in particular and the properties of the generalized
spectral decomposition have been studied. Resonances and resonance projections
for this map have been calculated explicitly.
