This works fine when the variable is of type
sage.symbolic.expression.Expression
but when I make the polynomial ring PolynomialRing(QQ, a), it breaks. Here
is the specific code:
a = var( 'a1comma2', latex_name='a_{ %d, %d }' % (1,2))
a; view(a); type(a);
a1comma2a1,2
<type 'sage.symbolic.expression.Expression'>
vars = PolynomialRing(QQ, a).gens(); vars; type(vars[0]); view(vars[0])
(a1comma2,)
<type
'sage.rings.polynomial.polynomial_rational_flint.Polynomial_rational_fli\
nt'>a1comma2
