... then r + f/∈ R p k or r + f ∈ R p ω . This is so because R n ⊆ R n+1 for every positive integer n. Moreover, if r ∈ R n ∩ (R p j \R p j+1 ) and f ∈ R n ∩ (R p j \R p j+1 ) for j  n − 1, then r ... R p n \R p n+1 or r + f ∈ R p ω . (2) For any r ∈ R and f ∈ R, height R (r + f) = min (height R (r) , height R (f)) holds. (3) R = R 0 × R 1...

... therefore M (r) =inf{m(B(z, r) ) : z ∈ J(f)} > 0 for every r& gt;0; see [8]. Consider c 0 ∈ ∂M d so that P c 0 is semihyperbolic, then all (finite) periodic points of P c 0 are repelling. Moreover, ... Let t>0. A probability measure m on J(f) is called t-conformal for f : C → C if m(f(A)) =  A |f  | t dm for every Borel set A ⊂ J(f) such that f | A is injective. A more general definit...
