Description (last modified by slelievre)

Following an initial report by Ask Sage user "Road" at

Define a polynomial ring and its generators:

sage: R = PolynomialRing(QQ, 'a, b, c')
sage: a, b, c = R.gens()

The generators display well:

sage: latex(a)  # good

Now define a quotient of that ring modulo an ideal:

sage: I = R.ideal(a**2 + a + 1)
sage: S = R.quotient(I, names=R.variable_names()).fraction_field()
sage: a, b, c = S.gens()

The generators display poorly:

sage: latex(a)  # should be same as above

Adding a _latex_ method in sage/rings/ addresses the issue.

This is done in this ticket.
