This book is intended to be a short introduction to uniqueness questions for initial value problems. One often weakens the notion of a solution to include non-differentiable solutions. Such a solution is called a weak solution. It is easier to find a weak solution, but it is more difficult to establish its uniqueness. This book examines three very fundamental equations: ordinary differential equations, scalar conservation laws, and Hamilton-Jacobi equations. Starting from the standard Gronwall inequality, this book discusses less regular ordinary differential equations. It includes an introduction of advanced topics like the theory of maximal monotone operators as well as what is called DiPerna-Lions theory, which is still an active research area. For conservation laws, the uniqueness of entropy solution, a special (discontinuous) weak solution is explained. For Hamilton-Jacobi equations, several uniqueness results are established for a viscosity solution, a kind of a non-differentiable weak solution. The uniqueness of discontinuous viscosity solution is also discussed. A detailed proof is given for each uniqueness statement. The reader is expected to learn various fundamental ideas and techniques in mathematical analysis for partial differential equations by establishing uniqueness. No prerequisite other than simple calculus and linear algebra is necessary. For the reader?s convenience, a list of basic terminology is given at the end of this book. 410 0$aCompact Textbooks in Mathematics,$x2296-455X 606 $aDifferential equations 606 $aDifferential Equations 606 $aEquacions d'evolució$2thub 608 $aLlibres electrònics$2thub 615 0$aDifferential equations. 615 14$aDifferential Equations. 615 7$aEquacions d'evolució 676 $a515.35 676 $a515.353 700 $aGiga$b Mi-Ho$0508456 701 $aGiga$b Yoshikazu$0499915 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910746081803321 996 $aBasic Guide to Uniqueness Problems for Evolutionary Differential Equations$94168229 997 $aUNINA
