Is there a name for a “rigid” sheaf?
The term "rigid sheaf" would potentially be confused with the notion of rigidity from deformation theory: a sheaf is rigid if it has no first order deformations, i.e. if $\mathrm{Ext}^1(F,F)=0$. I'm not sure of a term for what you are considering. |

Sum of digits of repeating end of reciprocal of prime over period is $\frac{9}{2}$
About 2/3rds of the first 10000 primes satisfy the property. |

It's false for $p=31$. I can't really explain why it holds for smaller $p$, besides that $9/2$ should be the most common average digit value since it is the average of the 10 base 10 digits. |

why do automorphisms preserve ample divisors?
Consider $\mathbb{P}^1\times \mathbb{P}^1$ embedded by an "unbalanced" divisor. The involution does not act trivially on the divisor. |
