Symmetry Festival – Sofia 2021

 Dear Colleagues: 

 Because of the worldwide outbreak situation, almost all scientific, sport and other international social activities are postponed for next year. 

 The Organizing Committee in Sofia, together with the Executive Board of the International Symmetry Association (ISA), postpones the Symmetry Festival for 9-12 July 2021. The program for the Festival remains the same. Thanks to those, who already submitted their extended abstract and registration form. The registration fees are valid for next year (the same online platform for registration will re-open again in January 2021). 

 I am looking forward to meeting you in Sofia! 

 Kind regards, 

 Ruslan I. Kostov
