Free Resolutions, Linkage, and Representation Theory_1
We review the construction of the generic ring R_gen for finite free resolutions of length 3. We describe the connection to the root system of type T_pqr. This gives a multiplicity free decomposition of R_gen as an sl(F_0) x sl(F_2) x g(T_pqr) module. We define the defect Lie algebra and higher structure maps. Several concrete examples will be given.
