Quadratic equation-condition for positiveness what is the condition for the positiveness of the quadratic function $A u+B u^2+C u^3$ is always positive for all $0<u<1$.
One writes $$ Au + Bu^2 + Cu^3 = u (A+ Bu + Cu^2) $$ and concludes that, in order to fullfill the positiveness condition, the quadratic expression $$ A

True or false? Positiveness of the parameter of the moment generating function We have a random variable with expected value $\mathbb{E}\left [X \right] < 0$, paired with a parameter $\theta \neq 0$. The expectation $...
The moment generating function $f:t\mapsto E[e^{t X}]$ is convex, so its graph lies above all its tangent lines, including the one tangent at $(0,f(0))$. In particular $f(\theta)\ge f(0)+f'(0)\theta$. The mgf also has the property that its derivatives, evaluated at $0$, are the moments of $X$, so th...

Strict positiveness on a C*-algebra given by generators and relations. Let $A$ be a C*-algebra with generators $a_1,a_2,\ldots,a_n$ and some (non-important) relations (the relations imply that $\|a_i\|\leq 1$, so that...
Let $\phi$ be a state. Suppose that $\phi(a_1)=0$. Then, for some fixed $j$, $$ 0\leq\phi(a_ja_j^*)\leq\phi(a_1)=0, $$ so $\phi(a_ja_j^*)=0$. Now, since $\phi$ is completely positive, it satisfies the Kadison-Schwarz inequality; thus $$\tag{1} 0\leq\phi(a_j)\phi(a_j)^*\leq\phi(a_ja_j^*)=0, $$ so $\p...

Non-uniqueness of linear function extension with cone positiveness Let $M$ be a proper linear subspace of $\mathbb R^n,$ and let $K$ be a cone in $\mathbb R^n$ without the origin ($K$ may not be convex and for any $x ...
Counterexample: In $\mathbb R^2,$ let $K=\\{(x,y):y>0\\},$ $M=\\{(x,x): x\in \mathbb R\\}.$ Let $f(x,y)=y.$ Then $f>0$ on $K.$ Suppose $g$ is linear and $g>0$ on $K$ and $g=f$ on $M.$ Because $g>0$ on $K,$ $g(x,y)=cy$ for some $c>0.$ Because $g=f$ on $M,$ we have $g(1,1)=c=f(1,1)=1.$ Therefore $c=1,...

How to prove a norm on three dimensional space Show that $||(x,y,z)||=|x| + 2 \sqrt{(y^2+z^2)}$ is a norm on $\mathbb R^3 $. Sketch the unit ball. I have to show the positiveness, homogeneity and triangle inequality ...
For the triangle inequality, you have to prove: $$\lvert x+x'\rvert+2\sqrt{(y+y')^2+(z+z')^2}\leq\lvert x\rvert+2\sqrt{y^2+z^2}+\lvert x'\rvert+2\sqrt{y'^2+z'^2}$$ This amounts to proving: \begin{align*} \sqrt{(y+y')^2+(z+z')^2}&\leq \sqrt{y^2+z^2}+\sqrt{y'^2+z'^2}\\\ \iff(y+y')^2+(z+z')^2&\leq y^2+...

How about $x\cdot|x|$? That avoids the need for piecewise definition. And if $|x|$ is defined piecewise for you, then you can use $x\sqrt{x^2},$ instead.

Is $B - B'$ self-adjoint provided $B,B'$ are positive operators? If I have two positive operators $B,B'$ on an arbitrary Hilbert space $\mathcal{H}$ not necessarily over $\mathbb{C}$, how do I know that $B - B'$ is se...
As Daniel Fischer said: if this is how positivity is defined, and if the ground field is $\mathbb R$, then the statement is false. Just let $B'$ be the zero operator, and let $B$ be any non-self-adjoint positive operator such as $$\begin{pmatrix} 2 & 1 \\\ 0 & 2 \end{pmatrix}$$ The authors either im...
