Examples

import vcsn
ctx = vcsn.context('lal_char, q')
poly = lambda p: ctx.polynomial(p)
poly('a+b') + poly('a+b')

$\left\langle 2\right\rangle a \oplus \left\langle 2\right\rangle b$

poly('<2>a') + poly('<3>a')

$\left\langle 5\right\rangle a$

poly('<2>a') + poly('<3>a') + poly('<-5>a')

$\emptyset$

poly('<2>a') + poly('\z')

$\left\langle 2\right\rangle a$
