### Ordinary partitions vs partitions into odd parts

For what it worth, here is a combinatorial proof. We start with a known Lemma 1. Let $m$ be an even positive integer. Then the number of permutations of $[m]$ with only odd cycles equals to the number ...

### Reference request for a preprint by Effros-Ruan

I am not sure that requests for filesharing are appropriate for MO, but in this case I think I can justify it to myself, because the preprint you refer to was (probably) the one that became the ...

### Integration against Eisenstein series can be regarded as a cup product

Yes, that does indeed sound like something I might have said :) I was referring to some extremely powerful theorems, originally due to Michael Harris, which show that: The cohomology groups of ...

### Reference request for combinatorial problem related to $\max$ relation

I also don't have a reference, but I think one should be able to do this fairly explicitly as follows [it appears that Peter Taylor alludes to this strategy in their comment above]: First, note that ...

### Extending Hölder functions

I think that for the $C^{k, \alpha}(A)$ space, where $A$ is bounded and the regularity of its boundary is $C^{k, \alpha}$ as well, an extension theorem holds: see for example Theorem 4 in Brian Krumme'...
