Modules with strange decomposition properties
It is well-known that modules with pathological properties can be obtained by constructing modules with \nearly prescribed" endomorphism rings. (See, for example, [5], [2], [3], or [10].) Here we shall investigate that method using a rather weak notion of nearly prescribing the endomorphism ring, namely one that just requires that a certain ring be algebraically closed in the endomorphism ring ...
متن کاملThe Zassenhaus Decomposition for the Orthogonal Group: Properties and Applications
The orthogonal group of a quadratic space over a field has been the focus of intensive research over the past fifty years. As this article will indicate, it continues to be a source of interesting problems. Zassenhaus [17] constructed a decomposition for any element in the orthogonal group of a non-degenerate quadratic space over a field of characteristic not 2. This paper will develop the fund...
متن کاملThe strange case of a sub - DLA with very little HI
We report a deep search for HI 21cm emission from the z = 0.00632 sub-DLA toward PG1216+069 with the Giant Metrewave Radio Telescope. No emission was detected and our 5σ upper limit on the mass of any associated galaxy is MHI . 107 M⊙, nearly 3 orders of magnitude less than M⋆HI. The z ∼ 0.006 absorber is thus the most extreme known deviation from the standard paradigm in which high column dens...
متن کاملProperties of Cement Pastes Doped with Very High Amounts of Ground Granulated Blast-furnace Slag
In the current work, the properties of cement pastes doped with high amounts of ground granulated blast-furnace slag (HVS) were investigated. Portland cement (PC) was substituted with ground granulated blast-furnace slag (donated as slag) at very high amounts of 85%, 90%, 95% and 100%, by weight. PC paste without any content of slag was used as a reference. Some fresh and hardened properties su...
