Description (last modified by )
Gives a minimal implementation of the A_oo
Cartan type:
sage: CartanType(['A',oo]) ['A', oo] sage: CartanType(['A',oo]).is_irreducible() True sage: CartanType(['A',oo]).is_simply_laced() True sage: print(CartanType(['A', oo]).ascii_art()) ...---O---O---O---O---O---O---O---... -3 -2 -1 0 1 2 3
In addition, the ficket fixes the following error:
sage: CartanType(['A',-1]) File "<string>", line unknown ^ SyntaxError: unexpected EOF while parsing
