Summaries

I like to write summaries of things I learn or calculations that I do so I can go back in the future when I need it again. I thought I could share them in case people find them useful. I know I like to read it when I find something like that on other people's webpages. Let me know if you read some of them and find mistakes or things unclear.

(Lie groups) This one is a review of how to find the dimension of the usual Lie groups and Lie algebras that we encounter in physics.
(Symmetric tensors) Here is a calculation of the number of independent components in a totally symmetric tensor and in a totally anti symmetric tensor.
(Webpage building) I lead a session with the high energy theory people on how to build a webpage and the summary of what I said is here.
(2d torus blocks) I show here how to calculate the torus one-point function conformal blocks in two dimensions to reproduce the result of hep-th/0911.2353 that was not totally clear.
(Casimirs) This is a summary of the Casimir operators of the conformal algebra in general dimensions. It includes the quartic Casimir as well as the 2d version of the operators.
(Thermal objects) Here are some examples of objects in physics that exhibit periodicity in Euclidean time that can be related to finite temperature.
(Characters) I compute the contribution to the partition function from a single conformal familly in various settings.
