Bi-Hamiltonian structures for integrable systems on regular time scales
Blazej M. Szablikowski, Maciej Blaszak, and Burcu Silindir A construction of the bi-Hamiltonian structures for integrable systems on regular time scales is presented. The trace functional on an algebra of delta-pseudodifferential operators, valid on an arbitrary regular time scale, is introduced. The linear Poisson tensors and the related Hamiltonians are d ...

Hill's equation with random forcing parameters: The limit of delta function barriers
Fred C. Adams and Anthony M. Bloch This paper considers random Hill's equations in the limit where the periodic forcing function becomes a Dirac delta function. For this class of equations, the forcing strength q, the oscillation frequency lambda, and the period (Deltatau) are allowed to vary from cycle to cycle. Such equations arise ... [J. Math. Phys. 50, 073501 (2009)] published Thu Jul 2, 2009.
Quasiperiodic solutions for the cubic complex GinzburgLandau equation
Hongzi Cong, Jianjun Liu, and Xiaoping Yuan The existence of two-dimensional KolmogorovArnoldMoser invariant tori is proved for cubic complex GinzburgLandau equation of higher spatial dimension. As a consequence, the equation possesses a Cantorian branch of nontraveling-wave quasiperiodic solutions of two-dimensional frequency vector. ... [J. Math. Phys. 50, 063516 (2009)] published Tue Jun 30, 2009.
