2018-05-22 16:36:23 +0200	commented question	Evaluating the error "Can only substitute elements of positive valuation" Is there no way to evaluate, even if it's just a numeric approximation the power-series at a value of z?
2018-05-21 19:15:33 +0200	asked a question	Evaluating the error "Can only substitute elements of positive valuation" I'm trying to work with sage's weierstrass_p function for elliptic curves, and I'm getting an error that I can't interpret. This is what I'm running, `E = EllipticCurve('11a1') WP = E.weierstrass_p() L = E.lseries() WP(L(1))` The error I'm getting is "Can only substitute elements of positive valuation" And I just don't know why sage doesn't want to evaluate the function at the given value. Any thoughts would be really appreciated!
