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 ...

let $mathcal{a}$ be a banach algebra and $mathcal{m}$ be a banach $mathcal{a}$-bimodule. we say that a linear mapping $delta:mathcal{a} rightarrow mathcal{m}$ is a generalized $sigma$-derivation whenever there exists a $sigma$-derivation $d:mathcal{a} rightarrow mathcal{m}$ such that $delta(ab) = delta(a)sigma(b) + sigma(a)d(b)$, for all $a,b in mathcal{a}$. giving some facts concerning general...

A classical cryptosystem and a public-key cryptosystem are proposed, based on the passing from a string of production labels (embedding in some way the message to be encrypted) to the string generated by the grammar by a (leftmost) derivation with that given control word (thus obtaining the cyphertext). Some problems of formal language theory appearing in this framework are discussed.

the sciences of syntax, reading, and interpretation are among the literary arts that are made by clerics for understanding the word of god (kalāmollāh) from various viewpoints, and from which a collection of 30 scientific disciplines called quranic literature developed. at the top of these sciences is “using diacritical marks in quran” which is extremely important. in this area, many noted scho...

In this paper, we describe a new reranking strategy named word lattice reranking, for the task of joint Chinese word segmentation and part-of-speech (POS) tagging. As a derivation of the forest reranking for parsing (Huang, 2008), this strategy reranks on the pruned word lattice, which potentially contains much more candidates while using less storage, compared with the traditional n-best list ...

The goal of this paper is to explore some consequences of the dichotomy between competence and performance from the point of view of incrementality. We introduce a TAG–based formalism that encodes a strong notion of incrementality directly into the operations of the formal system. A leftassociative operation is used to build a lexicon of extended elementary trees. Extended elementary trees allo...

We examine noun phrases and predication in Khoekhoe, a Central Khoisan language, arguing that members of all open word classes can function equally and without derivation as predicates, and that predicative use is primary and referential use is derived syntactically by relativization. We then present a formal HPSG analysis, in which members of all open word classes enter the syntax as predicate...

In this paper we investigate the status of various word-formation rules relating to the derivation of the agentive deverbal nominalization in Slovenian by examining the speakers' perception of pseudo-words that violate these rules. The experiment, based on Manouilidou's (2007) investigation of Modern Greek, includes 20 native speakers of Slovenian. The results show that, contrary to Greek speak...
