SL2 Seminar

In this talk, we will put together all ingredients we have seen in the last couple of talks to describe the algorithm to calculate tilting characters for reductive algebraic groups in the anti-spherical module. We will try to illustrate the most important steps of the algorithm by an example calculation for $SL_3$ (using Soergel calculus). In the end, we will mention current obstacles limiting our calculations and show some results.
