comment derivative of log determinant of the product of matrices
1) This is a site for professionals. Don't use 'u', 'i', 'log lik' etc. 2) We have LaTeX for a reason. I think I haven't mangled what you were asking. 3) Why do you keep using an identity matrix in expressions? Totally unnecessary. 4) Why do you want this thing? Why do you just need a hint? Where did it arise? What do you know already? 5) Did you know about stats.stackexchange.com ? Don't cross post this there, by the way. 6) See mathoverflow.net/help/how-to-ask, and if you ask future questions at stats.SE, keep those points in mind there.

Are they sequences of real numbers? Do you know anything at all?

comment A Cube has side 10, what is the distance between the intersection point of the four diagonal and a vertex?
Wrong site. See math.stackexchange.com (check out other questions here and see if yours really fits here :-)

Just leave it here. It's a good record of how people responded.

comment Gauge-theoretic formulation of Maxwell equations
@Urs I gather the OP is after a calculation that takes d*F=0 and dF=0 and outputs what a physicist would recognise as Maxwell's equations.

@ZurabSilagadze thanks for that reference. I've voted to close this question as a duplicate, given the wealth of answers there.

comment Gauge-theoretic formulation of Maxwell equations
Please, please don't use dollar signs and \textit{} to make text italic. Simple underscores will work here; use \emph{} if you are writing a paper.

Do you mean a round sphere?

comment Lawvere's “Some thoughts on the future of category theory.”
youtube.com/playlist?list=PLRIsuk3ZOitzDqeVKOZhe0MrzEUtRNAh5 is a video of the actual talk. It is, from the few minutes I've watched, less overtly philosopical.
