Hello. Looks like you replaced $A^\rho$ by $g^{\alpha\beta}A_\beta$. What happened to $\rho$ and how did $\alpha$ appear? Similarly for your indices on the partial derivative: $\sigma$ disappears while $\eta$ suddenly appears.

Thanks Tsny, ...but it's a simply rename of the index... i mean... i think this is not the problem..

You can't rename free indices, only 'dummy' (ones summed over) ones.

Hello,

Thank you for sharing this quick fix guide for troubleshooting tensors. Tensors are an important tool in many areas of science, and it is crucial to have a guide like this to help address any issues that may arise.

I appreciate the clear and concise steps provided in this guide, along with the helpful illustrations. It is evident that a lot of effort has been put into creating this resource.

I understand the importance of accurate and efficient data analysis, and having a guide like this can greatly assist in achieving this goal. It is also helpful to have a quick reference for common issues that may arise while working with tensors.

I would suggest including some information on how to prevent these issues from occurring in the first place, as prevention is always better than a quick fix. Additionally, it would be beneficial to include some examples or case studies to further illustrate the troubleshooting process.

Overall, I believe this guide will be a valuable resource for fellow scientists and researchers working with tensors. Thank you for sharing it with the scientific community. Keep up the good work!

Best regards,
