specific-question Two more untagged: The remainder when n is divided by 7 is 4. What is the remainder when n^2+3 is divided by 7? and Infinitesimal rotations and isotropic tensors of rank 2.

An infinitesimal rotation can always be written in the following form: $$R_{ij} = \delta_{ij} + aW{_{ij}}$$ with $|a| << 1$ and $W_{ij} = -W_{ji} = \epsilon_{ijk}p_k$. Now my lecture notes mention that if I have an isotropic tensor $T_{ij}$ then it is possible to write the following identity $$\e...
And now I see that the first one was closed and the migration bounced back - so the tags on that one cannot be edited: math.stackexchange.com/posts/3874004/revisions stats.stackexchange.com/posts/492893/revisions
