Is this a homework problem? If so, it should go in the appropriate homework forum, and the homework template should be filled out.

Also, formulas should not be pasted in as images; they should be done using the PF LaTeX feature. Otherwise it's impossible for people to quote your formulas properly when responding.
 
No, this is not a homework, I just learn by myself. thank you for your suggestion.
 
If you generated your equations using LaTeX, simply enclose the code for each equation between $$ delimiters on each side (for standalone equations) or ## delimiters (for "inline" equations, embedded inside a paragraph).
 
We also don't know how to calculate the term, because you don't give us what this omega is. Because omega is antisymmetric, the summation however simplifies, because only ##\frac{1}{2}D(D-1)## components of it are independent.
 
To answer the original question, you have to tell us what you want to achieve. I don't understand what you mean by "how to calculate it". It's just the expression you wrote down, what else should it be?
 
In Philippe G. Ciarlet's book 'An introduction to differential geometry', He gives the integrability conditions of the differential equations like this: $$ \partial_{i} F_{lj}=L^p_{ij} F_{lp},\,\,\,F_{ij}(x_0)=F^0_{ij}. $$ The integrability conditions for the existence of a global solution ##F_{lj}## is: $$ R^i_{jkl}\equiv\partial_k L^i_{jl}-\partial_l L^i_{jk}+L^h_{jl} L^i_{hk}-L^h_{jk} L^i_{hl}=0 $$ Then from the equation: $$\nabla_b e_a= \Gamma^c_{ab} e_c$$ Using cartesian basis ## e_I...
Abstract The gravitational-wave signal GW250114 was observed by the two LIGO detectors with a network matched-filter signal-to-noise ratio of 80. The signal was emitted by the coalescence of two black holes with near-equal masses ## m_1=33.6_{-0.8}^{+1.2} M_{⊙} ## and ## m_2=32.2_{-1. 3}^{+0.8} M_{⊙}##, and small spins ##\chi_{1,2}\leq 0.26 ## (90% credibility) and negligible eccentricity ##e⁢\leq 0.03.## Postmerger data excluding the peak region are consistent with the dominant quadrupolar...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. The Relativator was sold by (as printed) Atomic Laboratories, Inc. 3086 Claremont Ave, Berkeley 5, California , which seems to be a division of Cenco Instruments (Central Scientific Company)...
