Dotting a Sphere What is the maximum number of points that you can place symmetrically on the surface of a sphere which cannot all be contained within two planes? "Symmetrically" here means that, for any given start ...
I'm not sure what your question is exactly, but I interpret it as this. Consider a finite set $A$ of points on the sphere $S^2$. We want it to have the property that for each two points $a$, $b\in A$, there is a rotation $R\in O(3)$ with $Ra=b$ and $R(A)=A$. So each of these $R$ lies in the proper i...

Dot product with vector and its transpose? I'm having trouble with the statement: $$||\textbf{v}||^2=\textbf{v}\cdot\textbf{v}=\textbf{v}^T\textbf{v}$$ taking $\textbf{v}$ as a column vector in an orthogonal matrix. H...
The dot product "$\cdot$" is also known as scalar product and is defined as the sum of pairwise multiplication: $$\textbf v\cdot \textbf v = \sum_{i=1}^n\textbf v_i^2$$ The last part of the inequality is a matrix multiplication. Because of their dimension ($1\times n$ and $n\times 1$), the result wi...

By dotting, the author probably means that $\vec{a} .\vec{b} = a^Tb$, for _vectors_ $a$ and $b$, so
$(Ax)^Ty = (Ax).y$,
and $x^T(A^T y ) = x.

How do I use the given vector equation to resolve vector $p$ into a parallel and perpendicular component? I am working on the following problem: \frac{q}{\|q\|}=\frac{p\cdot q}{\|q\|^2}q$$ i.e. $$\frac{(3,-2,-1)\cdot(2,-2,3)}{2^2+(-2)^2+3^2}(2,-2,3)=\frac{7}{17}(2,-2,3).$$ ...

If a, b, c are non coplanar unit vectors.. Such that $ a \times (b \times c) =\frac{ b + c}{\sqrt{2}}$ prove the angle between a, b is 3/4pi. I really don't want open the thing with vector so i cross both sidrs first...
You must use the rule for triple vector product: $$ a\times(b\times c)=b(a\cdot c)-c(a\cdot b)=b\cos\gamma - c\cos\beta, $$ where $\gamma$ and $\beta$ are the angles formed by $a$ with $c$ and $b$. Comparing that with $a\times(b\times c)=(b+c)/\sqrt2$ we get then: $$ \cos\gamma={1\over\sqrt2},\quad ...

Unitary matrices Suppose $U$ is a unitary operator, $A$ a vector self-adjoint operator and $v$ a fixed vector. Is it true that $U[v\cdot (U^\dagger A U)]^2U^\dagger$ equals to $(v\cdot A)^2$? I am mainly confused beca...
Given the context,the answer is _yes_. Let's consider just one "component" of the full vector of operators. $$U[v_x U^\dagger A_x U][v_x U^\dagger A_x U]U^\dagger = v_x^2 A_x^2$$ since you get a lot of $UU^\dagger$ or $U^\dagger U$ (which are all 1). The logic extends to when the full vector of oper...
