Today's photo follows in the theme of "What am I?", a photo of books in my office. This photo is also taken from my desk -- in this case, a paper I've been reading.
Yes, I do this all day, every day. Taking photos is a very nice break from all of the math! Mega bonus points to anyone who can identify the specific topic I'm studying in this paper. For a "hint" (which probably won't help!), this particular equation is showing the equivalence of the trace inner product to the symplectic inner product, in certain circumstances.
I won't be posting for a day or two due to traveling to the Sisu Ski Fest in Ironwood, but I'll be taking photos the whole time.
