In the past years, many physical problems in almost all branches of sciences and engineering were with success modelled using the concept of fractional order derivative. This subject has therefore fascinated consideration of many researchers around humankind. Particularly, the advantages of the concept of fractional calculus and their associated models via differential partial differential equations linking fractional order integrodifferential operators and their appliances have been previously intensively investigated with great success during the last years.

Despite the fact that the exploration of the phenomena is portrayed by interface of many organisms, the microreplications play an important role, and as result the computers turn out to be progressively scientific apparatus. The main reason for this special issue was to report and review the latest progress in the areas of partial differential equations. This special issue included in particular the following:(i)fractional partial differential equations and their applications in sciences and engineering,(ii)modelling and simulation of real world phenomena with partial differential equations,(iii)analytical and numerical methods for partial differential equations,(iv)new applications of iterations method,(v)anomalous diffusion.

We have received many submissions, however, to keep the standard high only few were accepted for publications. This special issue includes papers on dissimilar features, for instance, analysis of Sturm-Liouville Eigen-problems, numerical methods and analysis, iterative methods, fractional boundary value problems, analytical method like Lie symmetry analysis, and integral transform operators.

Evidently, it is not imaginable to satisfactorily distinguish in this special issue all the strategy of up-to-date exploration in fractional partial differential equations with their applications; however, we assumed that this special isssue contents both hypothetical investigate and significant progress including contemporary challenging problems, new ideas, and open problems.
