It is shown that the N=2 superconformal transformations are restricted N=1 supergauge transformations of a supergauge theory with Osp(2,2) as a gauge group. Based on this result, a canonical derivation of the Osp(2,2) current algebra in the superchiral gauge formulation of N=2 supergravity is presented.

this paper investigates the nature of absolutive case and the syntactic mechanisms underlying its licensing. to this end, two recent minimalist approaches to the syntactic derivation of ergative structure will be introduced. drawing on evidence from the syntactic derivation of clauses with intransitive complex predicates in kurdish, it will be established that the absolutive case is checked by ...

In this paper, we modify the result of M. N. Daif [1] on multiplicative derivations in rings. He showed that derivation is additive by imposing certain conditions ring ℜ. Here, have proved above with lesser than for getting to be additive.

Abstract In this article, we define the following: Let N 0 {{\mathbb{N}}}_{0} be set of all nonnegative integers and D = ( d i ) ∈ D={\left({d}_{i})}_...

In this paper we consider the derivations for even part of the finitedimensional Hamiltonian superalgebra H over a field of prime characteristic. We first introduce an ideal N of H 0 and show that the derivation space from H 0 into W 0 can be obtained by the derivation space from N into W 0 , the even part of the generalized Witt superalgebra W . For further application we also give the generat...

Input Distance ( ) is introduced as a metric for propositional resolution derivations. If F = Ci is a formula and D is a clause, then (D;F) is de ned as minijD Cij. The for a derivation is the maximum of any clause in the derivation. Input Distance provides a re nement of the clause-width metric analyzed by Ben-Sasson and Wigderson (JACM 2001) in that it applies to families whose clause width g...
