Stein E
We present a certain geometrical interpretation of the natural numbers, where these numbers appear as joint products of 5and 3-multiples located at specified positions in a revolving chamber. Numbers without factors 2, 3 or 5 appear at eight such positions, and any prime number larger than 7 manifests at one of these eight positions after a specified amount of rotations of the chamber. Our appr...
متن کاملStein Points
An important task in computational statistics and machine learning is to approximate a posterior distribution p(x) with an empirical measure supported on a set of representative points {xi}i=1. This paper focuses on methods where the selection of points is essentially deterministic, with an emphasis on achieving accurate approximation when n is small. To this end, we present Stein Points. The i...
متن کاملYes Sir, no Sir, not much difference Sir.
OBJECTIVE To assess whether making the sender's knighthood explicit in a series of letters would have any detectable effect on the response. DESIGN A random sequence was generated by flipping a coin to determine whether a letter would have 'Sir Iain Chalmers' or 'Iain Chalmers' typed under the signature. This sequence was prepared independently of the preparation of an alphabetic list of the ...
متن کاملHolomorphic fiber bundle with Stein base and Stein fibers
A surjective holomorphic map Π : X → Y between complex spaces is said to be a Stein morphism, if for every point y ∈ Y , there exists an open neighborhood U of y such that Π(U) is Stein. In 1977, Skoda [12] showed that a locally trivial analytic fiber bundle Π : X → Ω with Stein base and Stein fibers is not necessarily a Stein manifold. Thus giving a negative answer to a conjecture proposed in ...
متن کاملAlgebraic Stein Varieties
It is well-known that the associated analytic space of an affine variety defined over complex number field is Stein but the converse is not true, that is, an algebraic Stein variety is not necessarily affine. In this talk, we will give sufficient and necessary conditions for an algebraic Stein variety to be affine. One of our results is that a quasi-projective variety Y defined over complex num...
