The college i go to has weekely "Math talks" where different math proffesers(forgive my spelling) take turns talking about different math subjects. And this weeks lecture was labled "The Trace Theorem and the Hadamard Determinant Theorem". Usually all of the math seminars go over my head, since im only in calc one. I was just curious though if any of yall had basic info on the subject.
As is often the case in mathematics there exist lots of thing with the same name.
Hadamard's Determinant solves some maximization problem on matrix determinants. This is done by Hadamard matrices (apparently), and they are are used in generating error correcting codes. If anyone knows ofsomething called the trace theorem that now seems appropriate perhaps they can take over.
