2016-06-16 01:04:27 +0100 | asked a question | Coercion from symbolic ring to Laurent series ring? Is there a good way to convert from a symbolic expression to a Laurent series ring? For example, if x is a symbolic variable and LSR is a laurent series ring, then sage produces an error for LSR(1/x) saying that the element is not integral. |
