ArrShiCatalanA

Shi-Catalan arrangement of type A with multiplicities

Syntax
ArrShiCatalanA(S: RING, k: INT, L: LIST): LIST

Description
This function constructs the Shi-Catalan arrangement of type A in the first k variables of the polynomial ring S with multiplicities L[1] and L[2].

Example
/**/ use S::=QQ[x,y,z];	
/**/ L:=[-1,2];
/**/ ArrShiCatalanA(S, 3, L);
[x -y,  x -z,  y -z,  x -y -1,  x -z -1,  y -z -1,  x -y +1,  x -y +2,  x -z +1,  x -z +2,  y -z +1,  y -z +2]
