 Feb 3 awarded Popular Question Dec 16 awarded Popular Question Jan 24 awarded Popular Question Jul 2 awarded Curious Jun 4 comment About inverse matrix in portfolio choice You are right. I had a typo. In the textbook, there is no 1/2 in Equation (*). Thanks.

It seems that even on the compact set, pointwise convergence does not imply uniform convergence. By the way, I would accept the comments as the answer (should you post it or them), since they are very helpful. Thank you. Apr 30 comment uniform convergence of continuous functions One quick question: is it right to argue that Convex combination of continuous functions is continuous $\Rightarrow C[0,1]$ is convex. Apr 30 comment uniform convergence of continuous functions Riesz representation theorem seems to apply to linear functionals. But C[0,1] meas all continuous functions on [0,1]. Am I wrong?

I basically proved that.
