In this paper, we consider a quasilinearwave equation having nonlinear damping and source terms and obtained global existence and blow up results under certain polynomial growth conditions on the nonlinear functions σi, βi, (i = 1, 2, ..., n), f and g. We obtain global existence result for positive initial energy solution using Galerkin approximation procedure and nonexistence (blow up) result using the technique introduced by Georgiev and Todorova (1994) with little modification for our problem.

A commutative semigroup of contractions S on a Hilbert space, ℌ, has a natural order and resultant net structure which defines stability, system dynamics, and α and ω limits for the flight vectors ℌ0. The space of 'pure' flight vectors - no nontrivial weakly stable components - are spanned by the ω limits of weakly-wandering vectors which are weakly Poisson recurrent. ℌ0 splits: ℌ0 = ℌm ⊕ ℌw, ℌw the weakly stable subspace and Hm the weakly Poisson recurrent space. ℌm = ⊕M(xτ, S) where M(xτ, S) is the closed subspace spanned by the weak limit points of xτ, {xτ} an orthonormal set of weakly-wandering vectors in ℌm. Examples illustrate the results.

This paper is concerned with the parameter estimation problem for discrete observed Chan-Karoli-Longstaff-Saunders model driven by small Levy noises. The explicit formula of the least squares estimators are obtained and the estimation error is given. By using Cauchy-Schwarz inequality, Gronwall's inequality, Markov inequality and dominated convergence, the consistency of the least squares estimators are proved when a small dispersion coefficient e → 0 and n → ∞ simultaneously. The simulation is made to verify the effectiveness of the estimators.
