Abstract: In Mathematics and the Sciences, partial differential equations (PDEs) are a many-faceted subject. Due to the variety of sources, there is a wide spectrum of different types of PDEs and there is no general theory concerning the solvability of all of them. This project aims to provide original approaches and techniques in the analysis of two themes within PDEs field: (a) boundary value problems and (b) the isolated singularity problem. Using as starting point several studies on PDEs involving (p,q)-Laplace type operators, the first objective of the project will focus on the investigation of the existence and asymptotic behavior of positive solutions for a boundary value problem involving more general inhomogeneous differential operators considered in an Orlicz-Sobolev setting. Motivated by the recent advances in the study of the isolated singularity problem for elliptic equations involving singular potentials, the second objective of the project will extend, to the case of systems of the same type, results regarding the existence and profiles near zero of their positive solutions. At the conclusion of the project the results will not only fill a gap in current knowledge in these fields, but will also have cross-disciplinary significance in areas such as mathematical physics, quantum mechanics, fluid dynamics or mathematical biology.
