 Jan8 accepted Square of Bernoulli Random Variable Jan8 comment Square of Bernoulli Random Variable Alright thanks a lot. Jan8 comment Square of Bernoulli Random Variable OK so I guess this isn't true if I shift the mean to be 0 so that $P_X(x)=\begin{cases} 1-p &\text{if } x=-p\\p & \text{if } x=1-p \end{cases}$. How can you handle it then? Jan8 comment Square of Bernoulli Random Variable Is this still the case if the distribution is not defined on the points {0,1} anymore? For example, if I shift the mean to be 0 so that $P_X(x)=\begin{cases} 1-p &\text{if } x=-p\\p & \text{if } x=1-p \end{cases}$ Jan8 revised Square of Bernoulli Random Variable added 25 characters in body Jan8 asked Square of Bernoulli Random Variable Mar24 comment Bounded Linear Operators Ya your definition seems a lot easier to use... however, I probably need to use the definition given in class. I'll readjust my proof accordingly. Mar24 comment Bounded Linear Operators Word for word from my book: $T$ bounded operator then $\\ \|T\|=\sup\{|\langle Tf,g\rangle|:\|f\| \le 1, \|g\| \le 1\}$. I don't understand why this doesn't hold in this case.. Mar24 comment Bounded Linear Operators Does this mean my steps are wrong?

Why is the $\sup$ taken over $\|x\|=1$?

Do I first take an open ball w.r.t $d_i$ and show that I can find an open ball w.r.t. $d$ contained in this ball, and then vice-versa (hopefully that makes sense)? Thanks very much for your help by the way.
