Maximal solution of differential equation
WebWhen you use NDSolve, the initial or boundary conditions you give must be sufficient to determine the solutions for the u i completely. When you use DSolve to find symbolic solutions to differential equations, you may specify fewer conditions. The reason is that DSolve automatically inserts arbitrary symbolic constants C [i] to represent degrees of … Web20 jan. 2012 · Interestingly, we will show that problem (1) may have minimal (maximal) solutions between given lower and upper solutions and not have the least …
