LET X=（X<sub>t</sub>,P<sup>x</sup>） be a right Markov process with state space （E,ε）, semigroup （P<sub>1</sub>） andresolvent （U<sup>q</sup>）. As in ref.[1, 2], we denote by Exc<sup>q</sup>（X ）, Dis<sup>q</sup>（X） and Con<sup>q</sup>（X） thecones of excessive, dissipative, conservative measures of X, respectively, and by S<sup>q</sup>（X） thecone of excessive functions of X. By convention we drop the superscript q when it is zero. LetMF be the set of all exact multiplicative functional of X. For any given M∈MF, writeE<sub>M</sub>:= {x∈E:P<sup>M<sub>0</sub> = 1</sup> = 1} and S<sub>M</sub>: = inf} t】0: M<sub>1</sub>= 0 } for the set of
