By applying operator splitting to a complicated model one can often split it into simpler problems that can be analyzed separately. In this book one studies operator splitting for a family of nonlinear evolution equations, including hyperbolic conservation laws and degenerate convection-diffusion equations. Common for these equations is the prevalence of rough, or non-smooth, solutions, e.g., shocks. Rigorous analysis is presented, showing that both semi-discrete and fully discrete splitting methods converge. For conservation laws, sharp error estimates are provided and for convection-diffusion equations one discusses a priori and a posteriori correction of entropy errors introduced by the splitting. Numerical methods include finite difference and finite volume methods as well as front tracking. The theory is illustrated by numerous examples. There is a dedicated web page that provides MATLAB codes for many of the examples. The book is suitable for graduate students and researchers in pure and applied mathematics, physics, and engineering.Differential equationsbicsscNumerical analysisbicsscNumerical analysismscPartial differential equationsmscOperator theorymscDifferential equationsNumerical analysisNumerical analysisPartial differential equationsOperator theory65-xx35-xx47-xxmscHolden Helge52245Karlsen Kenneth HvistendahlLie Knut-AndreasRisebro Nils Henrikch0018173BOOK9910151932203321Splitting methods for partial differential equations with rough solutions762630UNINA01554ngm 2200409 a 450 991070150620332120120402151523.0(CKB)5470000002420030(OCoLC)782955126(EXLCZ)99547000000242003020120402d2011 ma vengurmna|||m||||tdirdacontentcrdamediacrrdacarrierWays to cope with the fear of cancer returning[electronic resource][Bethesda, Md.] :[National Institutes of Health],[2011?]1 streaming video file (1 min., 56 sec.) digital, SWF file, sound, colorTitle from HTML title bar (viewed Apr. 2, 2012).Accompanied by transcript in HTML format.Julia Rowland, Ph.D., National Cancer Institute, outlines positive steps cancer patients can take during remission to manage anxiety about cancer's possible return.CancerPsychological aspectsPopular worksCancerPatientsMental healthPopular worksWorryPopular worksEducational films.lcgftCancerPsychological aspectsCancerPatientsMental healthWorryRowland Julia Howe1393686National Institutes of Health (U.S.)GPOGPOBOOK9910701506203321Ways to cope with the fear of cancer returning3483279UNINA
