Second International Workshop

Numerical Solution of Fractional Differential Equations and Applications


June 5 - 10, 2022, Sozopol, Bulgaria







The workshop is organized by the Institute of Information and Communication Technologies, Bulgarian Academy of Sciences and MIV Consult Ltd. in cooperation with Bulgarian Section of SIAM (BG SIAM) and the Center of Excellence in Informatics and Information and Communication Technologies (CoE in Informatics and ICT).


Organizing Committee

Silvia Grozdanova, Stanislav Harizanov, Raytcho Lazarov, Ivan Lirkov, Svetozar Margenov



The workshop is scheduled for June 5 - 10, 2022.



The NSFDE&A22 will be held in Sozopol (ancient Apolonia), a picturesque town on the Black Sea coast, 36 km south of Bourgas. The Bourgas International Airport is 50 km to the north from Sozopol.

The workshop will be organized as a hybrid event: a) presence at the conference venue in Sozopol; and b) online through the free (for the participants) software platform Zoom.



The workshop follows the great success of the first workshop NSFDE&A20 (, and the Special Sessions Fractional Diffusion Problems: Numerical Methods, Algorithms and Applications organized within the scientific program of the 12th and 13th LSSC Conferences (

The workshop is aimed to continue the new chain of NSFDE&A events to be organized biannually, every even year, complementary to the well-established LSSC conferences every odd year.



Specific topics of interest (but not limited to) are the following: (i) fractional in space diffusion problems; (ii) fractional in time diffusion problems; (iii) models of phenomena with memory; (iv) optimal control involving fractional diffusion; (v) analytical and semi-analytical solution methods; (vi) multigrid solvers; (vii) coupled problems; (viii) phase separation and image segmentation; (ix) parallel algorithms and HPC and big data tools; (x) applications in science and engineering.


Scientific Program

The Scientific Program of NSDDE&A22 includes regular talks of 30 min. and key-note talks of 45 min. The Program is available here.

Extended Abstracts/Short Communications

The extended abstracts/short communications (up to 3 pages) are to be written in standard LaTeX. The book is here.


Full Papers

We offer the opportunity for publication of selected papers presented at the workshop in the peer-reviewed open access journal: Int. J. Appl. Math. (IJAM),, indexed in Scopus (

An attractive way to organize your travel is to use a direct regular or charter flight to Burgas airport. There is a regular bus line 15 from Burgas airport to the bus station south, a starting point for the regular buses to Sozopol. Alternative way to the public bus is to rent a car or use a taxi from the Burgas airport.


Social Program

The social events will include a welcome reception on Monday (June 6) and a conference dinner on Wednesday (June 8).
