hyperdirichlet (version 1.4-8)

Arith-methods: Arith methods for hyperdirichlet objects

Description

Methods for Arithmetic functions on hyperdirichlet objects. There are only two operations:

• Add two of the same dimensions, as ina+b
• Multiply a hyperdirichlet object by a length-one scalar, as ina*5

Both these operations result in the normalization constant becoming unknown.

No unary operations are defined.

Value

• Arithmetic functions on hyperdirichlet objects return hyperdirichlet objects. Multiplication operates on the powers (not parameters), thus it is defined so that a+a = 2*a = a*2; associativity means that a+...+a ($n$ copies) equals n*a.
