Download E-books Integration of One-forms on P-adic Analytic Spaces. (AM-162) (Annals of Mathematics Studies) PDF

By Vladimir G. Berkovich

Among the various adjustments among classical and p-adic items, these concerning differential equations occupy a unique position. for instance, a closed p-adic analytic one-form outlined on a simply-connected area doesn't unavoidably have a primitive within the classification of analytic features. within the early Eighties, Robert Coleman stumbled on how to build primitives of analytic one-forms on convinced tender p-adic analytic curves in a much bigger classification of capabilities. in view that then, there were a number of makes an attempt to generalize his rules to delicate p-adic analytic areas of upper measurement, however the areas thought of have been at all times linked to algebraic varieties.

This ebook goals to teach that each delicate p-adic analytic house is supplied with a sheaf of capabilities that incorporates all analytic ones and satisfies a specialty estate. It additionally includes neighborhood primitives of all closed one-forms with coefficients within the sheaf that, within the case thought of by means of Coleman, coincide with these he developed. consequently, one constructs a parallel delivery of neighborhood options of a unipotent differential equation and an essential of a closed one-form alongside a course in order that either count nontrivially at the homotopy category of the trail.

Both the author's past effects on geometric houses of tender p-adic analytic areas and the idea of isocrystals are extra constructed during this ebook, that is aimed toward graduate scholars and mathematicians operating within the components of non-Archimedean analytic geometry, quantity conception, and algebraic geometry.

Download E-books Nonlinear Diffusion Equations PDF

By Huilai Li

Nonlinear diffusion equations, a tremendous category of parabolic equations, come from numerous diffusion phenomena which seem broadly in nature. they're prompt as mathematical types of actual difficulties in lots of fields, corresponding to filtration, part transition, biochemistry and dynamics of organic teams. in lots of instances, the equations own degeneracy or singularity. the looks of degeneracy or singularity makes the research extra concerned and hard. Many new principles and strategies were built to beat the precise problems because of the degeneracy and singularity, which increase the idea of partial differential equations. This publication offers a entire presentation of the elemental difficulties, major effects and standard tools for nonlinear diffusion equations with degeneracy. a few effects for equations with singularity are touched upon.

Download E-books Qualitative Analysis of Nonlinear Elliptic Partial Differential Equations (Contemporary Mathematics and Its Applications Book Series) PDF

By Vicentiu Radulescu

The ebook presents a accomplished creation to the mathematical idea of nonlinear difficulties defined through elliptic partial differential equations. those equations could be obvious as nonlinear models of the classical Laplace equation, and so they look as mathematical versions in numerous branches of physics, chemistry, biology, genetics and engineering and also are suitable in differential geometry and relativistic physics. a lot of the fashionable conception of such equations relies at the calculus of diversifications and practical research.

targeting single-valued or multivalued elliptic equations with nonlinearities of assorted forms, the purpose of this quantity is to acquire sharp lifestyles of nonexistence effects, in addition to decay premiums for normal periods of options. Many technically proper questions are provided and analyzed intimately. a scientific photograph of the main proper phenomena is acquired for the equations below learn, together with bifurcation, balance, asymptotic research, and optimum regularity of solutions.

Download E-books Frequency Methods in Oscillation Theory (Mathematics and Its Applications) PDF

This publication is dedicated to nonlocal conception of nonlinear oscillations. The frequency tools of investigating difficulties of cycle life in multidimensional analogues of Van der Pol equation, in dynamical platforms with cylindrical section house and dynamical structures pleasant Routh-Hurwitz generalized stipulations are systematically provided right here for the 1st time. to unravel those difficulties tools of Poincaré map building, frequency equipment, synthesis of Lyapunov direct equipment and bifurcation conception parts are utilized. V.M. Popov's strategy is hired for acquiring frequency standards, which estimate interval of oscillations. additionally, an method of examine the steadiness of cycles according to the information of Zhukovsky, Borg, Hartmann, and Olech is gifted, and the consequences showing while bounded trajectories are risky are mentioned. For chaotic oscillations theorems on localizations of attractors are given. the higher estimates of Hausdorff degree and measurement of attractors generalizing Doudy-Oesterle and Smith theorems are bought, illustrated via the instance of a Lorenz process and its varied generalizations. The analytical equipment built within the e-book is utilized to the research of oscillation of varied keep watch over platforms, pendulum-like structures and people of synchronization. viewers: This quantity should be of curiosity to these whose paintings comprises Fourier research, worldwide research, and research on manifolds, in addition to arithmetic of physics and mechanics ordinarily. A heritage in linear algebra and differential equations is thought.

Download E-books Time Frequency and Time-Scale Methodes PDF

By Jeffrey A. Hogan

Developed during this booklet are a number of deep connections among time-frequency (Fourier/Gabor) research and time-scale (wavelet) research, emphasizing the robust adaptive tools that emerge while separate recommendations from every one quarter are accurately assembled in a bigger context. whereas researchers on the leading edge of those parts are good conscious of the advantages of any such unified process, there continues to be an information hole within the greater neighborhood of practitioners in regards to the certain strengths and boundaries of Fourier/Gabor research as opposed to wavelets. This ebook fills that hole by means of providing the interface of time-frequency and time-scale equipment as a wealthy quarter of labor. "Foundations of Time-Frequency and Time-Scale Methods" may be appropriate for utilized mathematicians and engineers in signal/image processing and communique thought, in addition to researchers and scholars in mathematical research, sign research, and mathematical physics.
