ArrShiCatalanD

ArrShiCatalanD -- Shi-Catalan arrangement of type D with given multiplicities

Syntax

ArrShiCatalanD(S: RING, k: INT, L: LIST): LIST

Description

This function constructs the Shi-Catalan arrangement of type D 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];
/**/ ArrShiCatalanD(S, 2, L);
[x -y,  x +y,  x -y -1,  x +y -1,  x -y +1,  x -y +2,  x +y +1,  x +y +2]
