Thus, the reader is introduced to the fascinating theory around Brouwer's fixed point theorem, to Granas' theory of topological transversality, and to some advanced techniques of critical point theory and fixed point theory. Other topics include discontinuous differential equations, new results of metric fixed point theory, robust tracker design problems for various classes of nonlinear systems, and periodic solutions in computer virus propagation models. 606 $aMathematics & science$2bicssc 606 $aResearch & information: general$2bicssc 610 $aBanach contraction principle 610 $aBrouwer fixed point theorem 610 $achoquard equation 610 $acomputer virus model 610 $adifferential system 610 $adiscontinuous differential equations 610 $aDu-Hung's fixed point theorem 610 $ae0-metric 610 $aessential distance (e-distance) 610 $aessential maps 610 $aglobal minima 610 $agradient dependence 610 $aHamadard theorem 610 $ahomotopy 610 $ahybrid Taguchi real coded DNA algorithm 610 $aKrasnosel'skii?'s fixed point theorem 610 $a??-function 610 $a??(?)-function 610 $aminimax 610 $aminimax methods 610 $aMizoguchi-Takahashi's fixed point theorem 610 $amultiplicity 610 $an/a 610 $aNadler's fixed point theorem 610 $anehari method 610 $anonhomogeneous 610 $anonlinear elliptic problem 610 $ap-Laplacian 610 $aperiodic solutions 610 $aperturbation estimator 610 $aPID controller 610 $aPoincare?-miranda theorem 610 $apositive solution 610 $apositive solutions 610 $aRobin boundary condition 610 $aSEIR-KS model 610 $aselections 610 $asliding mode control 610 $asub-supersolution 610 $a?-function 615 7$aMathematics & science 615 7$aResearch & information: general 700 $aPrecup$b Radu$4edt$0737781 702 $aPrecup$b Radu$4oth 906 $aBOOK 912 $a9910557375203321 996 $aNonlinear Functional Analysis and Its Applications$93037685 997 $aUNINA
