Status of "OKA" experiment
Status of the " OKA " project: the experimental program with RF-separated K ± beam at U-70 Protvino, Russia, is presented. The early history of the project, current stutus of the beam-line and experimental facility are shortly described. Some results (mostly technical) from recent (April 2009) run are reported. Near-term plans and possible directions of the physical program are briefly discussed.
متن کاملAn Oka Principle for Stein G-manifolds
Let G be a reductive complex Lie group acting holomorphically on Stein manifolds X and Y . Let pX : X → QX and pY : Y → QY be the quotient mappings. Assume that we have a biholomorphism Q := QX → QY and an open cover {Ui} of Q and G-biholomorphisms Φi : p −1 X (Ui)→ p −1 Y (Ui) inducing the identity on Ui. There is a sheaf of groups A on Q such that the isomorphism classes of all possible Y is ...
متن کاملOka and Ako Ideal Families in Commutative Rings
In our earlier study [LR] of prime ideal principles in commutative rings, we have introduced the notion of Oka and Ako families of ideals, along with their “strong analogues”. The logical hierarchy between these ideal families (and the classically well-known monoidal families of ideals) was partly worked out in [LR] over general commutative rings. In the present paper, we amplify this study by ...
متن کاملMy 45 years of astrochemistry: memoirs of Takeshi Oka.
I decided to devote my research career to studies of interstellar molecules on December 17, 1968. On that day I read in the Sussex Library of the National Research Council of Canada (NRC) in Ottawa the December 16 issue of Physical Review Letters, in which the discovery of interstellar NH3 through radio emission between inversion levels of the J = K metastable NH3 was reported by the group of C...
متن کاملOn Oka ’ s extra - zero problem by M . Abe
After the solution of Cousin II problem by K. Oka III in 1939, he thought an extra-zero problem in 1945 (his posthumous paper) asking if it is possible to solve an arbitrarily given Cousin II problem adding some extra-zeros whose support is disjoint from the given one. By the secondly named author, some special case was affirmatively confirmed in dimension two and a counter-example in dimension...
