Could you please recommend conferences and Schools in 2020-2021 having Geometry (Symplectic, Lie theory) and topology (differential, low dimensional) as their main topics?
a bit off-topic, and it might not be your cup of tea, but in july, 2020, there will be an African Mathematical School in Medea, Algeria, on dynamics of switching systems, and applications to biology/ecology. If you know people in Ouargla who might be interested, would you be so kind as to pass the information ?
The International Society for Geometry and Graphics will have another conference in Sao Paulo, Brazil on January 18-22, 2021. They also publish the Journal for Geometry and Graphics. The Journals of Heldermann Verlag also publish the Journal of Lie Theory.
