5th Meeting on Commutative Algebra and Algebraic Geometry
August 12 – August 14 – IMPA
Our research group in Commutative Algebra and Algebraic Geometry (ALGA) is organizing the fifth meeting since 1997. This year we will meet from August 12 to 14 at IMPA, Rio de Janeiro, Brazil. This is a satellite meeting to the XVII Brazilian Algebra Meeting. The meeting will be special, as we will celebrate the sixtieth anniversaries of two mathematicians who greatly contributed to forming our group, Aron Simis (UFPE) and Steven Kleiman (MIT).
