Article about partitions with forbidden parts/multiplicities
Thank you, the last two articles are exactly what I was looking for. I appreciate your useful summaries that makes me recognize them immediately. I also appreciate your other links. |

How to isolate $f(x)$ in $f(x+a)=f(x)+a\times g(x)$?
You are actually trying to calculate the indefinite sum of terms defined by $f$ (just look at the case $a=1$), so you really should narrow down the class of functions to have summation algorithms. |

Two rectangular parallelepiped
@David Eppstein: What you write is absolutely correct, but note that in the OP we had rectangular parallelepipeds, so I mentioned the number of vertices to indicate that it is not necessary to think more about this in this case. Sorry for being both too lazy to repeat the word "rectangular" and to give the more general argument. I don't like the English term "rectangular parallelepiped". |

The first eigenvalue of a graph - what does it reflect?
They can also be the eigenvalues of the Laplacian of the graph. |
