comment resolving expected utility of st. petersburg paradox with logarithmic utility
thanks can you explain what is wrong with first computation, ie what is confused?

Why do you need the Span condition at all? I also don't understand the second $\iff$

comment Proving properties of linear maps on one-dimensional vectors
@GitGud: still don't follow how you get $Tv = av$? Is there a constructive way to derive that $a$ based on $T$ and the fact that the basis is one-dimensional?

@GitGud: an obvious basis for $R^{n}$ is $((1,0,0,...,0),(0,1,0,...,0), ...)$ for $n$ lists (i.e. 0 in all places except the $n$th). You can assume any basis for $R^{n}$ that you'd like though; not sure how this affects the question?
