1. On Peaked Periodic Waves to the Nonlinear Surface Wind Waves Equation.

Author

Bo, Jiang, Zhou, Youming, and Feng, Liu

Subjects
*WIND waves, *NONLINEAR systems, *EXISTENCE theorems, *DIFFERENTIAL equations, *WAVE equation
Abstract

We present a weak formulation of the nonlinear surface wind waves equation in the sense that the existence of peaked periodic waves as weak solutions is established by employing qualitative analysis for differential equations. Based on the theoretic results, we also present all possible exact explicit expressions of peaked periodic waves. [ABSTRACT FROM AUTHOR]

Abstract

Let E be a graph-directed set associated with a di-graph G . Let μ be a Markov-type measure on E . Assuming a separation condition for E , we determine the exact convergence order of the L r -quantization error for μ . This result provides us with accurate information on the asymptotics of the quantization error, especially when the quantization coefficient is infinite. [ABSTRACT FROM AUTHOR]
