As the preceding volumes, it is a collection of self-contained, state-of-the-art surveyswrittenbywell-knownexpertsinthefield. Thetopicscoveredbythisvolumeincludeinparticularsemilinearandsuperlinearellip- ticsystems,thefiberingmethodfornonlinearvariationalproblems,somenonlineareigen- valueproblems,thestudiesofthestationaryBoltzmannequationandtheGierer–Meinhardt system.Ihopethatthesesurveyswillbeusefulforbothbeginnersandexpertsandhelpto thediffusionoftheserecentdeepresultsinmathematicalscience. I would like to thank all the contributors for their elegant articles. I also thank Lauren SchultzYuhaszandMaraVos-SarmientoatElsevierfortheexcellenteditingworkofthis volume.
