Abstract Let $f:\mathbb {C}^2\to \mathbb {C}^2$ be a polynomial skew product that leaves invariant an attracting vertical line $ L $. Assume moreover $f$ restricted to $L$ is non-uniformly hyperbolic, in the sense satisfies one of following conditions: (1) $f|_L$ topological Collet–Eckmann and weak regularity conditions. (2) The Lyapunov exponent at every critical value point lying Julia set $f...

The Non-Deterministic and Polynomial Time Problem is a problem in combinatorial optimization. Finding the quickest route for an object to travel through list of cities return starting city goal this problem. Cities are listed, along with distance between each pair. It belongs category computer problems known as NP-complete problems, which no effective algorithmic solution has yet been discovere...
