DESCRIPTION:Date: April 15\, 2026 (Wednesday) at 4PM (UK time)\n\nSpeaker: 
	Prof. Harald Andrés Helfgott\, Paris City University\, France\n\nTopic: Gr
	owth\, expansion and escape in groups\n\nProf. Harald Helfgott is a leadin
	g mathematician who made fundamental contribution to number theory\, group
	 theory\, and additive combinatorics. He is widely known for his proof of 
	the ternary Goldbach conjecture\, as well as for foundational contribution
	s to the study of growth and expansion phenomena in groups. In this talk\,
	 he will discuss growth and expansion in groups\, including progress towar
	d the celebrated Babai conjecture on the diameters of finite simple groups
	. See the blog announcement of this talk for more details.\n\nLink to join
