When does the radius of convergence of the product of two $p$-adic power series increase?
Have you looked at "Rank one solvable p-adic differential equations and finite Abelian characters via Lubin–Tate groups" by Andrea Pulita? The abstract starts with "We introduce a new class of exponentials of Artin–Hasse type, called π-exponentials". |

Hodge-Tate representations
A simpler example would be a non-trivial extension of $Q_p$ by $Q_p(-1)$. |

Algebraic integer with conjugates on the unit circle
The same is true of $\alpha^k$ and the characteristic polynomials of the $\alpha^k$ have coeffts that are bounded indept of $k$. A lot of them must be equal to each other, so $\alpha^k = \alpha^\ell$ for some $k$ and $\ell$. |

Can an abelian variety/Q have no non-trivial points over Q_sol?
@Pablo sorry, my mistake! |

By definition, an abelian variety over a field K has a rational point over K, so in your question, you presumably mean a homogenous space for your abelian variety. |
