Complexity Theory Meet (Co-tMeet)
 |
This is an informal reading group organized by the complexity theory group. The group meets once a week (for Jul-Nov 2024, we meet on Wednesdays 3:30pm - 5pm) where a participant presents a paper or everyone watches a talk video as a group. The participants also collectively maintain a list of papers that they wish to see presented (at some point) or talks that they would like to propose to be watched in the group. Any participant can contribute to this list or volunteer for presenting one of the listed papers. Click here for volunteering to present a paper or adding a paper or a talk of your choice to this wish list. |
