Unbalancing

unbalancing'

Project documentation

An unbalancing lemma in physical space. Suppose ν\nu is a probability weight, ff is real-valued, and ff and ν\nu admit self-difference-convolution factorizations f=ggf=g\mathbin{\circleddash}g and ν=hh\nu=h\mathbin{\circleddash}h. If 0<ε10<\varepsilon\le1, p0p\ne0, and fLp(ν)ε\|f\|_{L^p(\nu)}\ge\varepsilon, then some integer pp' satisfies p210ε2pp'\le 2^{10}\varepsilon^{-2}p and 1+fLp(ν)1+ε/2\|1+f\|_{L^{p'}(\nu)}\ge1+\varepsilon/2.

Relative Ent Resource ne top

UnitalFreeStateTheory.relativeEntResource_ne_top

Plain-language statement

In a FreeStateTheory, we have free states of full rank, therefore the minimum relative entropy of any state ρ to a free state is finite.
