| Description | 
         
		Workshop web page is at THIS LINK. 
	The school will introduce commutative algebra and algebraic geometry in prime characteristics and their relationship with complex algebraic geometry. There have been many important developments in these fields during the last three decades. There will be four courses of lectures to highlight some of these developments related to vector bundles and tight closure, singularities in prime characteristics, F-signature and Hilbert-Kunz multiplicity and study of singularities via Big Cohen-Macaulay (BCM)-algebras, perfectoid spaces and Frobenius splitting. Topics: 
 Confirmed Speakers: Holger BRENNER, University of Osnabrueck, Germany 
		Ilya SMIRNOV, Basque Centre for Applied Mathematics, Spain 
	
		Kevin TUCKER, University of Illinois at Chicago, USA 
	
		Keiichi WATANABE, Nihon University, Tokyo, Japan 
	Grants: A limited number of grants are available to support the attendance of selected participants, with priority given to participants from developing countries. There is no registration fee.  |
