The study of the complexity of logical problems has provided a very fruitful field of research since many decades. On the one hand researchers have tried to classify exactly in terms of complexity classes and upper and lower bounds the complexity of decision and other logical problems. Although in general such problems are of high complexity, efforts have been made to develop efficient algorith...

The sequence space m(φ,∆m, p) of fuzzy real numbers for 0 < p < 1 and 1 ≤ p < ∞, are introduced. Some properties of the sequence space like solidness, symmetricity, convergence-free etc. are studied.

In this paper we describe a procedure for calculating the number of regular octahedra, RO(n), which have vertices with coordinates in the set {0, 1, ..., n}. As a result, we introduce a new sequence in The Online Encyclopedia of Integer Sequences (A178797) and list the first one hundred terms of it. We improve the method appeared in [12] which was used to find the number of regular tetrahedra w...

In 1996, Dontchev [14] introduced and investigated a new notion of non-continuity called contra-continuity. Recently, Baker et al. [6] offered a new generalization of contra-continuous functions via λ-closed sets, called almost contra λ-continuous functions. It is the objective of this paper to further study some more properties of such functions.

In this paper, we define a new concept, called N -group soft intersection action (SI) on a soft set. This new notion gathers soft set theory, set theory and N -group theory together and it shows how a soft set effects on an N -group structure in the mean of intersection and inclusion of sets. We then obtain its basic properties with illustrative examples and derive some analog of classical N -g...
