Realization of locally extended affine Lie algebras of type $A_1$
Locally extended affine Lie algebras were introduced by Morita and Yoshii in [J. Algebra 301(1) (2006), 59-81] as a natural generalization of extended affine Lie algebras. After that, various generalizations of these Lie algebras have been investigated by others. It is known that a locally extended affine Lie algebra can be recovered from its centerless core, i.e., the ideal generated by weight...
متن کاملOn Drinfeld Realization of Quantum Affine Algebras
In 1987 Drinfeld [Dr2] gave an extremely important realization of quantum affine algebras [Dr1][Jb]. This new realization has lead to numerous applications such as the vertex representations [FJ][J]. The proof of this realization was not in print until Beck’s braid group interpretation for the untwisted types [B]. Some of lower rank cases were also studied in [D][S]. All these work started from...

متن کاملGroup actions on affine cones
We address the following question: Determine the affine cones over smooth projective varieties which admit an action of a connected algebraic group different from the standard C∗-action by scalar matrices and its inverse action. We show in particular that the affine cones over anticanonically embedded smooth del Pezzo surfaces of degree ≥ 4 possess such an action. A question in [FZ1] whether th...
