Work over the complex numbers. For all triples $(X,\Delta,M)$, where $(X,\Delta)$ is an $n$-dimensional log smooth variety with $\Delta$ a reduced divisor and $M$ an ample Cartier…

Fujita's log spectrum conjecture. Under this notation,

Let $\xi\approx 2.30524$ be the unique positive root of $x^5-2x^4-x^2-x-1$, and let the accumulation points from above of a set of real numbers be limits approached by larger eleme…
