The aim of the workshop is to exchange the recent progress and ideas in the field of fractional calculus and fractional differential equations (FDEs), and their applications to a variety of concrete problems. Our group took an initiative to organise this workshop for the continuity of research in the field despite the coronavirus times, therefore, the conference will take place on ZOOM.

The work of our group on the fractional calculus can be seen here


Presentation of our group:

GAP presentation

There is also a forthcoming special issue on evolution equations with singularities.

If you work in analysis, there is still a possibility to submit a paper to the (refereed) volume: Ashyralyev A., Kalmenov T., Ruzhansky M., Sadybekov M., Suragan D. (Eds.) Functional Analysis in Interdisciplinary Applications II, Springer Proceedings in Mathematics & Statistics, Springer, to appear

Our modelling of COVID-19 for Belgium:

The effectiveness analysis is carried our for the lockdown in Belgium and of its duration, as well as of several phases of its relaxation. The comparative projection is made of different scenarios depending on the strength of confinement measures and their implementation.
