In the spirit of a previous study of the tetrahedral group $T \simeq A_4$, we
discuss a minimalist scheme to derive the neutrino mixing matrix using the
double tetrahedral group $T'$, the double cover of $T$. The new features are
three distinct 2-dimensional r... | arxiv topic:hep-ph |

math.CA
We show that if no $m$-plane contains almost all of an $m$-rectifiable set $E
\subset \R^{n}$, then there exists a single $(m - 1)$-plane $V$ such that the
radial projection of $E$ has positive $m$-dimensional measure from every point
outside $V$.
