Článek se zabývá dosavadním stavem bádání v oblasti dějin ekonomické vědy a činnosti československých ekonomů v období socialismu. Podává přehled o základních příspěvcích k tomuto tématu od počátku devadesátých let jak domácího, tak zahraničního původu. Detailněji se pak věnuje pracím Johanny Bockmanové, Jiřího Suka a Gila Eyala, zmiňuje taktéž nejnovější výzkumné projekty, které se tímto tématem zabývají. Závěrem autor nabízí přehled dostupných pramenů (archivních dokumentů i publikovaných pamětí), kterých lze využít k dalšímu výzkumu., The article examines the current state of research in the field of the history of economic sciences and activities of Czechoslovak economists in the era of socialism. It provides an overview of basic contributions, both domestic and foreign, on this topic since the 1990s, examining works of Johanna Bockman, Jiří Suk and Gil Eyal in a greater detail. It also mentions the latest research projects concerning this topic. In the end, the author offers a list of available sources (archival documents and published memoirs) which can be used in future research., Václav Rameš., and Obsahuje bibliografii a bibliografické odkazy
Let $\Lambda=\left(\begin{smallmatrix} A&M 0&B \end{smallmatrix}\right)$ be an Artin algebra. In view of the characterization of finitely generated Gorenstein injective $\Lambda$-modules under the condition that $M$ is a cocompatible $(A,B)$-bimodule, we establish a recollement of the stable category $\overline{\rm Ginj(\Lambda)}$. We also determine all strongly complete injective resolutions and all strongly Gorenstein injective modules over $\Lambda$., Chao Wang, Xiaoyan Yang., and Obsahuje bibliografii
Several characterizations of 0-distributive posets are obtained by using the prime ideals as well as the semiprime ideals. It is also proved that if every proper l-filter of a poset is contained in a proper semiprime filter, then it is 0-distributive. Further, the concept of a semiatom in 0-distributive posets is introduced and characterized in terms of dual atoms and also in terms of maximal annihilator. Moreover, semiatomic 0-distributive posets are defined and characterized. It is shown that a 0-distributive poset P is semiatomic if and only if the intersection of all non dense prime ideals of P equals (0]. Some counterexamples are also given.
The concept of a 0-ideal in 0-distributive posets is introduced. Several properties of 0-ideals in 0-distributive posets are established. Further, the interrelationships between 0-ideals and α-ideals in 0-distributive posets are investigated. Moreover, a characterization of prime ideals to be 0-ideals in 0-distributive posets is obtained in terms of non-dense ideals. It is shown that every 0-ideal of a 0-distributive meet semilattice is semiprime. Several counterexamples are discussed.
The relative cohomology Hdiff1(K(1|3), osp(2, 3);Dγ,µ(S1|3)) of the contact Lie superalgebra K(1|3) with coefficients in the space of differential operators Dγ,µ(S1|3) acting on tensor densities on S1|3, is calculated in N.Ben Fraj, I. Laraied, S. Omri (2013) and the generating 1-cocycles are expressed in terms of the infinitesimal super-Schwarzian derivative 1-cocycle s(Xf) = D1D2D3(f)α31/2, Xf \in K(1|3) which is invariant with respect to the conformal subsuperalgebra osp(2, 3) of K(1|3). In this work we study the supergroup case. We give an explicit construction of 1-cocycles of the group of contactomorphisms K(1|3) on the supercircle S1|3 generating the relative cohomology Hdiff1(K(1|3), PC(2, 3); Dγ,µ(S1|3) with coefficients in Dγ,µ(S1|3). We show that they possess properties similar to those of the super-Schwarzian derivative 1-cocycle S3(Φ) = EΦ-1 (D1(D2),D3)α31/2, Φ ∈ K(1|3) introduced by Radul which is invariant with respect to the conformal group PC(2, 3) of K(1|3). These cocycles are expressed in terms of S3(Φ) and possess its properties., Boujemaa Agrebaoui, Raja Hattab., and Obsahuje seznam literatury
In the year 2003 ten years passed since the Germanoslavica journal was re-established. In this connection the history of activity duration and its aims have been evaluated. The article conveys a complex view of the journal structure as it looked like under the guidance of Prof. A. Měšťan.
