The alternating presentation of Uq(gl2ˆ) from Freidel-Maillet algebras
An infinite dimensional algebra denoted A¯q that is isomorphic to a central extension of Uq+ - the positive part of Uq(sl2ˆ) - has been recently proposed by Paul Terwilliger. It provides an ‘alternating’ Poincaré-Birkhoff-Witt (PBW) basis besides the known Damiani's PBW basis built from positiv...
