The pointwise base-point-freeness conjecture for adjoint bundles

Let YY be a smooth projective variety, let yYy\in Y be a point, and let LL be a nef and big line bundle on YY. Assume that for every irreducible subvariety ZZ with yZYy\in Z\subsetneqq Y,

(LdimZ.Z)(dimY)dimZ,(L^{\dim Z}\mathbin{.}Z)\geqslant(\dim Y)^{\dim Z},

and that

(LdimY)>(dimY)dimY.(L^{\dim Y})>(\dim Y)^{\dim Y}.

The pointwise base-point-freeness conjecture. The adjoint line bundle KY+LK_Y+L is base point free at yy. The source presents this as a known generalization of Fujita's base point freeness conjecture; no resolution status for this precise formulation is supplied in the excerpt.
