diagram algebras, hecke algebras and decomposition numbers at
... It follows immediately from (2.6.2) and (2.6.1) that the family {ξ1 , σ1 , . . . , σn−1 } satisfies the relations (BRB). But the relations (BR) and τ σi τ −1 = σi+1 are similarly shown to follow from (BRB), whence we have a presentation of Γn . It remains to show that the ξi commute with each other. ...

Lie algebra cohomology and Macdonald`s conjectures
... This conjecture occupies a central place in my thesis. Although I did not succeed in finding a complete proof, I strived to explain what appears to be the most promising way to look at it. Generally, in this thesis I sought to compute the cohomology rings of several classes of Lie algebras, all inti ...

... On the other hand, the minimal polynomial of α over R is X 2 − 2 2X + 3, by the previous example. This shows that the minimal polynomial of α over K really depends on which K we use! Remark. I forgot to point out in the last lecture that in Proposition 1.1.4, the minimal polynomial f of α over K has ...
