dim {weyl}

The dimension of a weyl object

Description

The dimension of a weyl algebra is the number of variables needed; it is half the spray::arity(). The dimension of a Weyl algebra generated by \left\lbrace x_1,x_2,\ldots,x_n,\partial_{x_1},\partial_{x_2},\ldots,\partial_{x_n}\right\rbrace is n (not 2n).

Usage

## S3 method for class 'weyl'
dim(x)

Arguments

x

Object of class weyl

Value

Integer

Note

Empty spray objects give zero-dimensional weyl objects.
