Quasiexcellence implies strong generation

نویسندگان

چکیده

We prove that the bounded derived category of coherent sheaves on a quasicompact separated quasiexcellent scheme finite dimension has strong generator in sense Bondal-Van den Bergh. This extends recent result Neeman and is new even affine case. The main ingredient includes Gabber's weak local uniformization theorem notions boundedness descendability morphism schemes.

Strong continuity implies uniform sequential continuity

A . Uniform sequential continuity, a property classically equivalent to uniform continuity on compact sets, is shown, constructively, to be a consequence of strong continuity on a metric space. It is then shown that in the case of a separable metric space, in order to omit the word sequential from this result, it is necessary and sufficient to adopt a principle (BD-N) that is independent of Hey...

Restricted Strong Convexity Implies Weak Submodularity

We connect high-dimensional subset selection and submodular maximization. Our results extend the work of Das and Kempe (2011) from the setting of linear regression to arbitrary objective functions. For greedy feature selection, this connection allows us to obtain strong multiplicative performance bounds on several methods without statistical modeling assumptions. We also derive recovery guarant...

Multi-scale Analysis Implies Strong Dynamical Localization

In the present paper we prove that a variable energy multi-scale analysis implies dynamical localization in a strong (expectation) form. Thus we accomplish a goal of a long line of research. Ever since Anderson’s paper [5], the dynamics of waves in random media has been a subject of intensive research in mathematical physics. The breakthrough as far as mathematically rigorous results are concer...

Uniform Weak Implies Uniform Strong Persistence for Non-autonomous Semiflows

It is shown that, under two additional assumptions, uniformly weakly persistent semiflows are also uniformly strongly persistent even if they are non-autonomous. This result is applied to a time-heterogeneous model of S-I-R-S type for the spread of infectious childhood diseases. If some of the parameter functions are almost periodic, an almost sharp threshold result is obtained for uniform stro...

Mixing Implies Strong Lower Bounds for Space Bounded Learning

With any hypothesis class one can associate a bipartite graph whose vertices are the hypotheses H on one side and all possible labeled examples X on the other side, and an hypothesis is connected to all the labeled examples that are consistent with it. We call this graph the hypotheses graph. We prove that any hypothesis class whose hypotheses graph is mixing cannot be learned using less than 2...
