Intersection of free objects
And by the way, thanks for the reference! |

Intersection of free objects
Indeed, I know for the while only the proof given in Lothaire's $\textit{Combinatorics on words}$. The reason why I ask this is because I consider intersection of many other free (combinatorial) algebraic structures than monoids and I would hope that a categorical argument imply their freeness. Since this is not the case (see Jeremy's answer) the only way seems to proceed case by case. |

How universal is operadic approach to studying algebras?
What is the statement of the theorem that someone should prove? Besides, do you have an example of an algebraic structure which, like groups, cannot be straightforwardly captured by operads, but, unlike groups, a "sneaky" presentation of it makes that it can be? |

Aspherical operads
You call "monochromatic" any coloured operad on only one colour? The construction you describe is a classical construction from operads to PROs (see Operads and PROPs of M. Markl, Example 60). |

Equivalent paths in graphs
@ViditNanda: I think a "face" is a cycle here. |

Arithmetic product of symmetric functions: why is it integral?
How this product expresses on the monomial, elementary, and Schur bases of symmetric functions? |

Generating function of factorable binary words
Indeed, it seems that oeis.org/A056267 and oeis.org/A027375 are duplicate. |

Generating function of factorable binary words
Your are asking for primitive words over a binary alphabet. The coefficients of the generating series you are looking for are the ones of Sequence A056267 of the OEIS. (And please, make an effort in writing your question.) |
