An extension of the real semiring with multiple degrees of infinity
It is not exactly the same framework, but maybe you will be interested in this: computer.org/csdl/proceedings/lics/2013/5020/00/… It is also related with weighted automata and different orders of "infinity" |

Two sets of strings resulted from a set represented by binary and decimal code are in the same class of languages?
To detail the answer of Benjamin Steinberg: you have a transducer (i.e. an finite-state machine) that can change between binary and decimal representation. All the classes of languages you mentioned are preserved by applying a transducer, so the answer to your question is yes. |

Convergence of iterated stochastic matrices
I don't get the first line of your answer. Why the $n^{th}$ powers of the matrices $M_n$ would form a subsequence? It seems to be plain wrong, for instance for $1\times 1$ size, the constant sequence $1/2$ converges to $M=1/2$, but $1/2^n\to 0$ and $M\neq 0$. |

How do you prove that a subset of L is regular is L is regular?
in fact I cannot delete because it's accepted... |

@BenjaminSteinberg ok I'll adopt this behaviour in the future, and delete the answer here. |

@BenjaminSteinberg I thought it would be migrated to math.se together with my answer, I don't have the power to do so.. |

How do you prove that a subset of L is regular is L is regular?
This construction works in general, for any regular $L$. |

Proof of conjecture that permutation-free automata restrict the possible states visitable from a stringset sharing prefixes and infixes
It seems $R=\{q_0\}$ and $k=1$ yields easy counter-examples. |
