During this times, when conferences and workshops are held online, it is a good chance to experiment with visual books of abstracts. See the book of abstracts movie for the workshop that we have just organised:

Description
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 coronovirus times, therefore, the conference will take place on ZOOM.
The work of our group on the fractional calculus can be seen here
There is also a forthcoming special issue on evolution equations with singularities.

Various processes in nature are characterized by irregular equations, in particular, evolution ones. Such equations could have chaotic and unexpected behaviours of the solutions, causing singularities. Therefore, they are natural in the sciences. Singularities could appear in different characteristics of the models such as coefficients and data. The initial conditions stand for the data for the evolution equations. By having data and coefficients less regular or, even singular, we are facing the difficulties outside of the tools of the classical analysis. For this, we are developing different approaches and technics to deal with. Here, we are more concentrated in such approaches and technics. One of the technics is hidden in the theory of regularisations. By regularising distributional initial data and coefficients, we arrive at the smooth enough operators. Their further study comes down to well-studied problems. One thing needs to be controlled a regularisation parameter. The Special Issue Singularities in Evolution Equations is collecting new results and trends on these problems.
Potential topics include, but are not limited to:
- Singular evolution equations and very weak solutions;
- Partial differential equations with time- and space-irregular coefficients;
- Hyperbolic and parabolic type equations with distributional data.
Authors are invited to submit original, unpublished papers. Simultaneous submission to other publication venues is not permitted.
Guidelines for authors are the same as for regular issues. The guidelines file is available at https://www.elsevier.com/journals/chaos-solitons-and-fractals/0960-0779?generatepdf=true.
When submitting papers, authors must select VSI: Evolution Equations as the article type.

Educational schools activities
During the last year we have secured several grants for our educational activities for (PhD) students and early career researchers.
Our grants for educational activities:
| 2020 | Flemish Government Seasonal School: Singularities in science and engineering (€23,000) | ||
| 2020 | Flemish Government Doctoral School: Wave equations and tsunami propagation (€3,650) | ||
| 2019 | Flemish Government Doctoral School: Inverse Spectral and Scattering Problems (€4,000) | ||
Here is the first one that we have just organised. The other two are still to come.
Doctoral School on Inverse Spectral and Scattering Problems, 27 February – 10 March 2020, Ghent University, Belgium
Lie groups connection in Sao Carlos, Brazil
Serena Federico (UGent), Marianna Chatzakou (Imperial College London), and Wagner Augusto Almeida de Moraes (Curitiba Brazil) at the ICMC summer meeting on differential equations in Sao Carlos, Brazil, 3-5 February 2020. All three are working on different exciting problems related to the analysis on Lie groups!
Dr Nurgissa Yessirkegenov
Nurgissa Yessirkegenov has successfully defended his PhD thesis “Function spaces on Lie groups and applications” at Imperial College London.
Congratulations Nurgissa!
Doctoral school on inverse spectral and scattering problems
Inverse problems for differential operators are of the utmost importance in fundamental sciences and in a range of applications, including solutions of different types of partial and pseudo differential equations. We are dealing with inverse spectral and inverse scattering problems, which are both interesting topics on their own and as tools in solving the wide range of linear and nonlinear problems, appearing in natural sciences, economics and industry.
We will be organising a course on this topic From Monday 2 March to Wednesday 11 March 2020 from 10h00 – 13h00.
Lecturer:
Prof. Igor Trushin, Department of Mathematics, Faculty of Sciences , Shinshu University, Japan
