  Beginners Explorations in Algebraic Geometry (formerly Elementary Algebraic Geometry) is a Graduate Center seminar for students and faculty in a form of a problem session. Contact Malgorzata Marciniak (mmarciniak@lagcc.cuny.edu) for questions and schedule.


DURING FALL 2017 WE WILL MEET ON TUESDAYS 12:30-1:30 PM IN GC 4214.03. "Tea time" is scheduled for 12 pm and 1:30 pm.


 The first (organizational) meeting is scheduled on September 12 and the last meeting on December 5, excluding September 19 and November 21 for irregular schedules.
We will follow Chapter 1, 2, and 4 from the book by Joseph Silverman The Arithmetic of Dynamical Systems, Graduate Texts in Mathematics 241, 2007
We will use CoCalc (SAGE) or another software to solve and illustrate problems that we pose or find in the book. All presentations are “hands-on” with the emphasis on posing questions and making attempts.
