Singular Manual: makeUso11

| ##### 7.5.10.0. makeUso11 Procedure from library `ncalg.lib` (see ncalg_lib). Usage: makeUso11([p]); p an optional integer (field characteristic) Return: a ring, describing U(so_{11}) Note: You have to activate this ring with the 'setring' command. The presentation of U(so_{11}) is derived from the Chevalley representation of so_{11}, positive resp. negative roots are denoted by x(i) resp. y(i); Cartan elements are denoted by h(i). Example:
    LIB "ncalg.lib";
    def ncAlgebra = makeUso11();
    ncAlgebra;
    ==> // coefficients: QQ
    ==> // number of vars : 55
    ==> //        block   1 : ordering dp
