Dear Organizers, My name is Marat Siddikov, I am a researcher from Chile. I would like to participate in your conference and give a talk in one of the parallel sessions. Today I've noticed an announcement on the conference website that the event will be held in person, and that those who cannot attend in person should contact the organizing committee in advance. I will not be able to participate in person due to COVID-related travel restrictions. I wonder if there is a possibility to participate in the conference online? Thanks in advance, Sincerely, Marat Siddikov
