let  be a banach algebra. let  be linear mappings on . first we demonstrate a theorem concerning the continuity of double derivations; especially that all of -double derivations are continuous on semi-simple banach algebras, in certain case. afterwards we define a new vocabulary called “-higher double derivation” and present a relation between this subject and derivations and finally give some ...

Abstract The system presented in this paper is concerned with the computational processing of the selected types of Czech word-formation. The developed programming tool (word-formation module) aims at analysing and synthesising Czech derived words. Such a system is of particular value for automatic processing of Czech language where derivational morphology plays an important role in regular wor...

In the present paper, we describe the development of the lexical network DeriNet, which captures core word-formation relations on the set of around 266 thousand Czech lexemes. The network is currently limited to derivational relations because derivation is the most frequent and most productive word-formation process in Czech. This limitation is reflected in the architecture of the network: each...

Kambaata, a Cushitic language of Ethiopia, has productive, word-class changing approximation derivation. The process marked by the suffix -lab takes adjectival, nominal and verbal roots as inputs generates approximatives that belong to adjective word class, whose members are characterised their agreement behaviour in NP. meaning Kambaata is dependent on class its input. Deadjectival express vag...

This study is to analyzes the type of word formation process terms in online shops. Thisresearch used descriptive qualitative. The result analysis shows four types wordformation shops, namely derivation, compounding, clipping, and acronym.The derivation forming words by giving affixes word, so results newword causes a change word-class its meaning. examples suffix are -er,-or, -al, -ment, -ed, ...

To maintain understanding, usage, and interrelations of English vocabularies by Iraqi second language learners (L2) is a challenging mission. In the current study, cognitive linguistic theory domains Langacker (1987) adopted to provide new horizons in learning vocabulary qualify students with deep knowledge analysis meanings lexical concepts. This paper aims test validity expanding for from Ira...

The article explores the geographic, stylistic and pragmatic evolution of lexical unit firana (‘curtain’) from a diachronic perspective, using data dictionaries, digital libraries corpora Polish language. author points out that this word is an example derivation called “truncation”, presents it as dialect, regional (Poznań origin) augmentative word. researcher draws attention to use in literatu...

Tree controlled grammars are context-free grammars where the associated language only contains those terminal words which have a derivation where the word of any level of the corresponding derivation tree belongs to a given regular language. We present some results on the power of such grammars where we restrict the regular languages to some known subclasses of the family of regular languages.

In his thesis, Remmers [R], introduced semigroup derivation diagrams and used them to prove that the word problem for finitely presented C(3) semigroups was solvable. In this article we introduce the annular analog of semigroup derivation diagrams and use them to demonstrate the solution to a conjugacy problem for finitely presented C(3) semigroups.
