### What is the meaning of this!!

Hello every one, I am a user of Sagemath online, I wrote theses below lines to find the steady state of my problem, But at the end I have no result except this []!! I would like to know what this means? It means there is no solution for this system equations? I put my lines here. Thank so much if anyone could help me. var ('Omegabar Qbar ') Ybar=1 pbeta=.99 epsilon=-1 sigma=.03 theta=.3 k=13 delta=.025 rho=1.1 Ybar=1; Lambdabar=pbeta Rlbar=1+1/Qbar Rbar=1/pbeta Rebar=1/pbeta munbar=LambdabarOmegabarRbar musbar=LambdabarOmegabar(Rlbar-Rbar) muebar=LambdabarOmegabar(1-pbeta) epersbar=musbar/muebar xbar=-epersbar+(epersbar^(2)+(2/k)(1-epsilonepersbar))^(1/2) Thetabar=theta(1+epsilonxbar+(k/2)xbar^(2)) phibar=Omegabar/(Thetabar-musbar-xbarmuebar) Ebar=xbarQbar Nbar=Qbar/phibar Dbar=Qbar-Nbar-Ebar Nnbar=delta(Qbar+Ybar)
