JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.https://encyclopedia.thefreedictionary.com/Teleparallelism So I just wonder why you say ##e_a## is orthonormal. But although GR gave...

JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.In the original definition of teleparalle connection, ##e_a## should be a holonomic frame(coordinate basis field), It is not necessarily...
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.So where is my wrong? just the conclusion is wrong？
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Then why you don't think that assumption is even consistent with his calculation? can you give me some explaination?
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.When you say the result from my calculation is wrong. then you should point out where I have made a mistake. If you are serious , you...

JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.The difference between me and ergospherical is that he didn't demand the basis field is a coordinate basis, so they assert that there...
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.So how to explain my result? if you think my explaination is wrong. then tell me the right one to explain the result I gave.

JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Don't hurry, if we start from the definition of Levi-Civita connection: ##\Gamma_{abc} = \frac{1}{2}(g_{ab,c} + g_{ac,b} - g_{bc,a})##...

JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Are you serious to say so? If my answers is obviously wrong, then it is very easy to point out where is my wrong. In fact the...
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.If you find that in my calculation I said if the basis field is a coordinate basis field, then it just means we only apply a coordinate...
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Is there any book tell us that a metric field can also be compatible with zero-curvature teleparallel connection? How to get the...
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.But does it means in all cases they can not be equal? Is there anything wrong in my calculations? And you tell me the partial...
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.If the basis field ##e_a={e_a}^I e_I## is not a coordinate basis, then it means that: ##{c_{ab}}^c e_c = [e_a, e_b]\neq 0## Using...
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.So ##e_a^J## should be a tetrad field. then from the equation: ##\partial_a {e_b}^{I} = {\Gamma^c}_{ab} {e_c}^{I}## If ##e_a^J## is a...
-
JJianbing_Shao replied to the thread I A sufficient condition for integrability of equation ##\nabla g=0##.Because compatible is defined with metric compatible equation, and this equation is different with the normal differential equation in...
