Opis:
The aim of this paper is to prove that derivations of a C*-algebra A can be characterized in the space of all linear continuous operators T : A → A by the conditions T(1) = 0, T(L∩R) ⊂ L + R for any closed left ideal L and right ideal R. As a corollary we get an extension of the result of Kadison [5] on local derivations in W*-algebras. Stronger results of this kind are proved under some additional conditions on the cohomologies of A.

Opis:
Let R be a prime ring with its Utumi ring of quotients U, C = Z(U) be the extended centroid of R, H and G two generalized derivations of R, L a noncentral Lie ideal of R, I a nonzero ideal of R. The left annihilator of S ⊆ R is denoted by lR(S) and defined by lR(S) = {x ∈ R| xS = 0}. Suppose that S = {H(un)un +unG(un) | u ∈ L} and T = {H(xn)xn +xnG(xn) | x ∈ I}, where n ≥ 1 is a fixed integer. In the paper, we investigate the cases when the sets lR(S) and lR(T) are nonzero.

In one of our former papers Endomorphisms of the measure algebra of commutative hypergroups we considered exponential monomials on hypergroups and higher order derivations of the corresponding measure algebra. Continuing with this, we are now looking for the connection between the generalized exponential polynomials of a commutative hypergroup and the higher order derivations of the corresponding measure algebra.

Opis:
In this paper, we place some left restrictions on derivations in CD grammar systems with phrase- structure grammars, controlled by the regular languages. The first restriction requires that every production is always applied within the first k nonterminals in every sentential form, for some $k \ge 1$. The second restriction says how many blocks of non-terminals can be in each sentential form. The third restriction extends the second restriction and says how many blocks of non-terminals with limited length can be in each sentential form. We demonstrate that under these restrictions, the grammar systems generate different families of languages. Indeed, under the first restriction, these systems generate only context-free languages. Under the second restriction, even one-component systems characterize the entire family of recursively enumerable languages. In the end, the family of languages generated by grammar systems under the third restriction is equal to the family of languages generated by programmed grammars with context-free rules without $\epsilon$- rules of nite index.

Opis:
Backderivation is an example of a non-affixative word-forming process in which an affix is removed to create a semantically corresponding verb (Bauer, Lieber, Plague 2013: 280). This common phenomenon in English mostly occurs in the area of lexis borrowed from classical languages. The author focuses on directionality as a diachronic problem, and productivity of the process in a synchronic perspective. In order to trace the phenomenon of directionality, material from the source languages is collected chronologically. As for the phenomenon of productivity, quantitative analysis bases on attestations in text corpora and dictionaries. The author examines occurrences of this mechanism and its influence on the creation of similar forms in scientific and specialist language.

Opis:
There is ongoing discussion about how to conceptualize the nature of the distinction between inflection and derivation. A common approach relies on qualitative differences in the semantic relationship between inflectionally versus derivationally related words: inflection yields ways to discuss the same concept in different syntactic contexts, while derivation gives rise to words for related concepts. This differential can be expected to manifest in the predictability of word frequency between words that are related derivationally or inflectionally: predicting the token frequency of a word based on information about its base form or about related words should be easier when the two words are in an inflectional relationship, rather than a derivational one. We compare prediction error magnitude for statistical models of token frequency based on distributional and frequency information of inflectionally or derivationally related words in French. The results conform to expectations: it is easier to predict the frequency of a word from properties of an inflectionally related word than from those of a derivationally related word. Prediction error provides a quantitative, continuous method to explore differences between individual processes and differences yielded by employing different predicting information, which in turn can be used to draw conclusions about the nature and manifestation of the inflection–derivation distinction.

Opis:
Greenberg’s Universal 28 says that ‘if both the derivation and inflection follow the root, or they both precede the root, the derivation is always between the root and the inflection’ (Greenberg 1966: 93). Booij (1994: 27) undermines this by allowing inherent inflection to feed derivation. There is abundant literature showing that inherent inflection can feed derivation in Germanic, Romance and Slavic languages (Booij 1994, 1996, Chapman 1996, Rainer 1996, Cetnarowska 1999). The aim of this paper is to describe and compare derivational categories related to participle forms in Irish and Polish. These include among others agent nouns, adjectives of tendency/inclination, resultative passive adjectives and facilitative adjectives. Stump (2005: 52) points out that the terms present and past participle are, in fact, misnomers since participles are uninflected for tense, and they should be regarded as stems conveying aspect information plus the lexical information of the root. The existence of derivatives based on inflected forms is usually taken as evidence against the inflection-derivation dichotomy, and in favour of a tripartition into contextual inflection, inherent inflection and derivation. The paper addresses the theoretical ramifications of the existence of such derivatives for inferential-realisational approaches (Stump 2001), such as for example Beard’s (1995) Lexeme-Morpheme Base Morphology, which separates the operations on the grammatical (morpholexical and morphosyntactic) features and operations responsible for the morphophonological modification of the root/stem.

Propagating scattered context grammars are used to generate sentences of languages defined by scatterd context grammars followed by the strings corresponding to the derivation trees. It is proved that for every language defined by a scattered context grammar, there exists a propagating scattered context grammar whose language consists of original language sentences followed by strings representing their derivation trees.

Opis:
The present article is an empirical, data-oriented study which focuses on the problem of morphological conversion and the way this mechanism was employed in Old English as a way of deriving new lexemes. The article briefly discusses the quantitative characteristics of the attested types, presents patterns of directionality and estimates the degree of availability of conversion in Old English grammar. The main part and purpose of the study, however, concerns the semantic characteristics of conversions sampled in the corpus. Drawing on the framework of semantic categories formulated by Clark and Clark (1979) and Plag (2003), the study aims to demonstrate semantic effects of the so-called zero-affix in Old English by looking into the relation that holds between the motivating base and the resultant derivative. Despite the fact that the availability of conversion was still quite limited in the Old English period, possibly due to numerous inflections that may have inhibited the transparency of this process, the study allows us to see how this process emerged and subsequently developed into one of the most productive word-formational techniques in the English language.
