Derive concentration bound for the derivative
Why on Earth would you expect this for general $f$, given that the derivative may not even exist? |

Is it true that all stationary measurable stochastic processes are “measurably stationary”?
Of course you can. But the idea is pretty much standard anyway... |

There is indeed such a map, under the assumptions that a) $X$ generates the whole σ-algebra on $\Omega$, b) $(\Omega,\mathcal{F},\mathsf{P})$ is standard (see the references in en.wikipedia.org/wiki/…). But we don't actually need it. Please see the updated answer... |

Does exterior product commute functor Hom?
@DinhVanHoang: My comment still applies. For infinite-dimensional vector spaces, for instance, $\mathrm{Hom}(\wedge^2 M, R)$ consists of all skew-symmetric matrices, while $\wedge^2 \mathrm{Hom}(M, R)$ only contains those of finite rank. |

Results true in a dimension and false for higher dimensions
Contraction in Hilbert space, I suppose? |

I strongly suspect that it's false even for infinite-dimensional vector spaces over fields. Did you check that? |

Is the ideal of functions vanishing at a set complementable in $C(X)$?
@SergeiAkbarov: Actually, it is. $\mathbb{N} \subset \beta \mathbb{N}$ consists of isolated points, so it's open. And in any case, your ideal $I$ only depends on the closure of the set. |
