Todays challenge:
What is the multidimensional screening
problem?
How to find the symmetry group and the invariants of this group?
If I can do that what does the typography look like?

2) How to find the symmetry group and the invariants of this group?
"group theoretic methods establish symmetry transformations that leave the screening problem unchanged, then seek the solution as a function of the invariants of these transformations."p.3
"One can observe that the larger is the set of transformations that leave the problem intact (technically known as the symmetry group) the smaller is the number of independent functions that are invariant under the set of transformations."(Basov, WTJN p.4)
"Therefore, one might conjecture that if the symmetry group becomes large there would remain just one invariant of the group, i.e. the type of the agent can be aggregated in one number and the screening problem will become unidimensional."(Basov, WTJN p.4)
Would be good to work this out with some concrete examples. More homework :)
