Which version of sage. On which os ? how installed ? Please copy the full traceback.

either use conda or build from source ; see https://doc.sagemath.org/html/en/installation/index.html

and your "fcn" is much too complicated, it could be written in one line..

Like that maybe def isoposet(P): U = [po for liste in iso(P).values() for po in liste] UU = Poset((U,fcn), cove

Like that maybe def isoposet(P): U= [po for liste in iso(P).values() for po in liste] UU=Poset((U,fcn), cover_r

Maybe using instead from pathlib import Path data = Path("C:\Users\etc").open() Beware of the slash versus backslash

Like this for just the set of isoclasses. def iso(P): D = {} for x, y in P.relations(): Q = P.subposet(

Try to reproduce it directly in maxima, and then file a bug in maxima bug-tracker.

Looks like a bug. Try to find a smaller instance if you can.

Modular form computation Error messages Me and my colleague ran the following computation: B=Cuspform(7x1381).q_integra

Here is a proposal, but not what you expect, I guess : sage: A = algebras.Free(QQ,list('XYZ'),degrees=(1,1,1)) sage: Ah

Like that sage: Ra=PolynomialRing(QQ,'a',6) ....: Fa=Ra.fraction_field() ....: a=Ra.gens() sage: r1=(a[1]^2+a[2])/(a[3]

Your function has no return anywhere. You should rather make a function taking a triple as input and returning a triple.

for example sage: integral(cos(1+i*t), (t,0,1),algorithm='fricas') 1/2*((e^(2*I) - 1)*e^(-I + 1) + e^(-I + 2) - e^I)*e^

sage 9.1 is very obsolete, but recent sage cannot do this integral

Are you using an old version of sage ? On a recent one, the result is sage: integrate(1/((x-a)^(1/2)*x^(3/4)),x,a,oo) N

make a matrix with the first 100 coefficients of a basis + your modular form and ask for the kernel.

Polyhedral geometry and floating point numbers are not really friends of each other.

There is no rsk method on element of SymmetricGroup(n): sage: s=SymmetricGroup(4).random_element() sage: t=Permutations

if you use the console you can switch to %display unicode_art

yes, right. You can use git grep to find where a function or method is defined, or look carefully at Par.arm_length?? wh
