On initial-boundary value problem for the Burgers equation in nonlinearly degenerating domain
AbstractIn this paper, we study the solvability of one initial-boundary value problem for the Burgers equation with periodic boundary conditions in a nonlinearly degenerating domain. In this paper, we found an orthonormal basis for domains with time-varying boundaries. On this basis, we use the Faedo–Galerkin method to prove theorems about the unique solvability of the problem under consideration. We also present some numerical results in the form of graphs of solutions to the problem under study for various initial data.Keywords: Burgers equationperiodic boundary conditionsdegenerating domainGalerkin methodMathematics Subject Classifications: 35K5535K1035R37 Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThe research of the second author was supported by the grant of the Science Committee of the Ministry of Science and Higher Education of the Republic of Kazakhstan, Project AP13067805.

期刊介绍:
Applicable Analysis is concerned primarily with analysis that has application to scientific and engineering problems. Papers should indicate clearly an application of the mathematics involved. On the other hand, papers that are primarily concerned with modeling rather than analysis are outside the scope of the journal
General areas of analysis that are welcomed contain the areas of differential equations, with emphasis on PDEs, and integral equations, nonlinear analysis, applied functional analysis, theoretical numerical analysis and approximation theory. Areas of application, for instance, include the use of homogenization theory for electromagnetic phenomena, acoustic vibrations and other problems with multiple space and time scales, inverse problems for medical imaging and geophysics, variational methods for moving boundary problems, convex analysis for theoretical mechanics and analytical methods for spatial bio-mathematical models.
