Anti-self Dual Part (2,2) Riemann Curvature Tensor

Click For Summary
SUMMARY

The discussion centers on the complexities of defining the anti-self dual part of the Riemann curvature tensor, particularly in relation to the Weyl curvature tensor. Participants highlight the need for clarity in definitions, especially regarding duals of tensors with anti-symmetric indices. The conversation emphasizes the importance of using the PF LaTeX feature for posting equations to facilitate better understanding. The distinction between left and right duals is noted, particularly under the condition of an Einstein metric.

TL;DR
Riemann curvature tensor has two pairs of anti-symmetric index. Is the double of Riemann tensor is Dual ? That how to define the anti self dual part of Riemann tensor.?
i am facing problems in the definition of dual oF some objects which has pair of anti symmetric indices e.g. Weyl curvature tensor. Double dual is there in the literature but given that how to find the anti self dual part of that. the problem is written in attached the file.

Not sure what the question is! You say you have a problem with a definition, but you haven't given a definition! Are you trying to figure out what the definition should be?! Where does all this come from and what is it for?

The Riemann tensor has two pairs of indices and you can use either of them to define a dual. Usually they are called the left and the right dual. If the metric is Einstein then they are equal.

This is not acceptable. Please use the PF LaTeX feature to post equations directly in the thread. There is a "LaTeX Guide" button at the lower left of the post window.
