On Whitham ’ s Averaging Method
Introduction. Whitham's averaged equations [1] for a nonlinear evolution system describe slow modulations of parameters on a family of periodic traveling wave solutions (or on families of multiphase quasiperiodic solutions, which are so far knows to exist only for integrable equations) and are a system of hydrodynamic type [2, 3], that is, of the form
متن کاملOn the asymptotic stability of discontinuous systems via averaging method
The averaging method is one of the most powerful methods used to analyse differential equations appearing in the study of nonlinear problems. The idea behind the averaging method is to replace the original equation by an averaged equation with simple structure and close solutions. A large number of practical problems leads to differential equations with discontinuous right-hand sides. In a rigo...
متن کاملA NOTE ON THE AVERAGING METHOD FOR DIFFERENTIAL EQUATIONS WITH MAXIMA
Substantiation of the averaging method for differential equations with maxima is presented. Two theorems on substantiates for differential equations with maxima are established.
متن کاملAn optimal first order method based on optimal quadratic averaging
In a recent paper, Bubeck, Lee, and Singh introduced a new first order method for minimizing smooth strongly convex functions. Their geometric descent algorithm, largely inspired by the ellipsoid method, enjoys the optimal linear rate of convergence. We show that the same iterate sequence is generated by a scheme that in each iteration computes an optimal average of quadratic lower-models of th...
متن کاملRotated Wedge Averaging Method for Junction Characterization
The computational cost of conventional lter methods for junction characterization is very high. This burden can be attenuated by using steerable lters. However, in order to achieve a high orientational selectivity to characterize complex junctions a large number of basis lters is necessary. From this results a yet too high computational eeort for steerable lters. In this paper we present a new ...
