| 2021-01-27 18:48:55 +0200 | asked a question | Extracting numerator of a Ricci tensor component Hello I'm solving Einstein equation in vacuum. I already computed the Ricci tensor. For example, de first Ricci component is saved in the following variable eq1: eq1=EE[0,0] The denominator of the component should vanish since since the other part of the equation is zero. How can I extract numerator of the expression. I have tried: eq1.denominator() But it does not work. Thanks |
