Partial $\ast$-algebras of distributions
2005
The problem of multiplying elements of the conjugate dual of certain kind of commutative generalized Hilbert algebras, which are dense in the set of C ∞ -vectors of a self-adjoint operator, is considered in the framework of the so-called duality method. The multiplication is defined by identifying each distribution with a multiplication operator acting on the natural rigged Hilbert space. Certain spaces, that are an
On formations of finite groups with the generalized Wielandt property for residuals II
2018
A formation [Formula: see text] of finite groups has the generalized Wielandt property for residuals, or [Formula: see text] is a GWP-formation, if the [Formula: see text]-residual of a group generated by two [Formula: see text]-subnormal subgroups is the subgroup generated by their [Formula: see text]-residuals. The main result of this paper describes a large family of GWP-formations to further the transparence of this kind of formations, and it can be regarded as a natural step toward the solution of the classification problem.
SOME SPECTRAL PROPERTIES OF MULTIPLIERS ON SEMI-PRIME BANACH ALGEBRAS
1995
Abstract We extend to arbitrary semi-prime Banach algebras some results of spectral theory and Fredholm theory obtained in [1] and [2] for multipliers defined in commutative semi-simple Banach algebras.
On a theorem of Berkovich
2002
In a recent paper, Berkovich studied how to describe the nilpotent residual of a group in terms of the nilpotent residuals of some of its subgroups. That study required the knowledge of the structure of the minimal nonnilpotent groups, also called Schmidt groups. The major aim of this paper is to show that this description could be obtained as a consequence of a more complete property, giving birth to some interesting generalizations. This purpose naturally led us to the study of a family of subgroup-closed saturated formations of nilpotent type. An innovative approach to these classes is provided.
GEOMETRIC EQUIVALENCE OF ALGEBRAS
2001
In this paper, we study the geometric equivalence of algebras in several varieties of algebras. We solve some of the problems formulated in [2], in particular, that of geometric equivalence for real-closed fields and finitely generated commutative groups.
Examples of improjective operators
2000
It has been an open question for some time whether improjective operators are always inessential. Here we give some examples that answer in the negative this question as well as some other related ones, posed in [2, 3, 11, 12]. The description of the examples uses a indecomposable space, constructed by Gowers and Maurey [5], and a characterization of the indecomposable Banach spaces in terms of improjective operators.
Nonlocalization Properties of Time Operators Transformations
2014
It is presented a general approach to the problem of extension of time operators and the associated Lambda transformations on singular measures. It is also shown that Lambda transformations defined on function spaces having the Urysohn property are non localized. Particular attention has been devoted to time and Lambda operators associated with the Walsh-Paley system and to a characterization of their domain and non locality.

2019
Sabiedrības vajadzībām nepieciešamā nekustamā īpašuma atsavināšanas likums paredz nekustamā īpašuma atsavināšanu sabiedrības vajadzībām labprātīgā vai piespiedu kārtā, saņemot taisnīgu atlīdzību. Pētījuma mērķis ir analizēt labprātīgas un piespiedu nekustamā īpašuma atsavināšanas sabiedrības vajadzībām procesa ietekmi uz taisnīgas atlīdzības noteikšanu nekustamā īpašuma īpašniekam. Iegūtie rezultāti liecina, ka slēdzot līgumu par labprātīgu nekustamā īpašuma atsavināšanu sabiedrības vajadzībām, nekustamā īpašuma īpašniekam ir lielākas iespējas iegūt taisnīgu atlīdzību Sabiedrības vajadzībām nepieciešamā nekustamā īpašuma atsavināšanas likuma kontekstā.
Do Overoptimistic Men Drive Creative Destruction? Evidence of Gendered Inventive Activity in Finland
2017
This study extends the analysis of the "patenting gender gap" into design rights and utility model (UMs), which are alternative methods for protecting intellectual property (IP). The analysis is descriptive and uses registry data from the Finnish patent and registration office (PRH) covering the years 1982–2013. A persistent gender gap is found for all intellectual property rights (IPRs): women are inventors and designers only in a small share of filings. The gap has narrowed over time for national patent and design right filings but not for UM filings. It is found that, in comparison to men, women are relatively less often individual inventors or designers and more often members of invento…
Pentafulvene durch Aminomethinylierung des Cyclopentadiens
1986
Aus der Dreikomponentenreaktion von Cyclopentadien (1) mit s-Triazin (2) und einem sekundaren Amin 4 gehen die cyclisch N,N-disubstituierten Pentafulven-6-amine 5 und die cyclisch N1,N1-disubstituierten N2-(6-Pentafulvenyl)formamidine 7 hervor. Unter den biologischen Eigenschaften der neuen Verbindungen ist besonders die anthelminthische Wirkung von 5d interessant. Pentafulvenes by Aminomethynylation of Cyclopentadiene The three component reaction comprising the interaction of cyclopentadiene (1) with s-triazine (2) and a secondary amine 4 leads to the cyclic N,N-disubstituted pentafulven-6-amines 5 and the cyclic N1,N1-disubstituted N2-(6-pentafulvenyl)formamidines 7.
