Negotiations, a model of concurrency with multi party negotiation as primitive, have been recently introduced in [5, 6]. We initiate the study of games for this model. We study coalition problems: can a given coalition of agents force that a negotiation terminates (resp. block the negotiation so that it goes on forever)?; can the coalition force a given outcome of the negotiation? We show that ...

In  this paper, we investigate the generalizedHyers-Ulam-Rassias stability for the quartic, cubic and additivefunctional equation$$f(x+ky)+f(x-ky)=k^2f(x+y)+k^2f(x-y)+(k^2-1)[k^2f(y)+k^2f(-y)-2f(x)]$$ ($k in mathbb{Z}-{0,pm1}$) in $p-$Banach spaces.

The aim of this paper is to investigate the boundedness and compactness Stevic-Sharma operator T?1,?2,? from QK(p, q) QK,0(p,q) spaces Zygmund-type space little space. We also give upper lower estimations for norm T?1,?2,?.

The HARMONY architecture [2] provides mechanisms for management of network and compute resources in a mobile computing environment. In HARMONY network resources are reserved based on the Entropy Model [7], and compute guarantees are provided by off-loading tasks from the mobile units to compute servers in the backbone network. A load-balancing scheme redistributes loads across all compute serve...

We study the target-space duality transformations in p–branes as transformations which mix the worldvolume field equations with Bianchi identities. We consider an (m + p + 1)-dimensional spacetime with p + 1 dimensions com-pactified, and a particular form of the background fields. We find that while a GL(2) = SL(2) × R group is realized when m = 0, only a two parameter group is realized when m ...

The set of morphisms φ : P → P of degree d is parametrized by an affine open subset Ratd of P . We consider the action of SL2 on Ratd induced by the conjugation action of SL2 on rational maps; that is, f ∈ SL2 acts on φ via φ = f ◦ φ ◦ f . The quotient space Md = Ratd/SL2 arises very naturally in the study of discrete dynamical systems on P. We prove that Md exists as an affine integral scheme ...

We continue the investigation of the computational power of spaceconstrained P systems. We show that only a constant amount of space is needed in order to simulate a polynomial-space bounded Turing machine. Due to this result, we propose an alternative definition of space complexity for P systems, where the amount of information contained in individual objects and membrane labels is also taken ...

in this paper, a certain new connectedness of l-fuzzy subsets inl-topological spaces is introduced and studied by means of preclosed sets. itpreserves some fundamental properties of connected set in general topology.especially the famous k. fan’s theorem holds.
