 In this paper, we have established some fixed fuzzy point theorems and common fixed fuzzy point theorems for fuzzy mappings satisfying a contractive type condition other than fuzzy Banach contractive type condition in complete fuzzy metric spaces.2010 Mathematics Subject Classifications: 47H10, 54E35, 54A40Kathmandu UniversityJournal of Science, Engineering and TechnologyVol. 12, No. 2, 2016, page: 34-49

Contractive conditions introduced in (Q. Zhang and Y. Song, Fixed point theory for generalized ?-weak contraction, Appl. Math. Lett. 22(2009), 75-78) and (D. Djoric, Common fixed point for generalized (?, ?)-weak contractions, Applied Mathematics Letters, 22(2009), 1896-1900) are employed to obtain a new common fixed point theorem for four maps. Our result substantially generalizes comparable results in the literature. 2010 Mathematics Subject Classifications. 47H10. .

The detour index of a connected graph is defined as the sum of detour distances between all unordered pairs of vertices. We determine the n-vertex unicyclic graphs whose vertices on its unique cycle all have degree at least three with the first, the second and the third smallest and largest detour indices respectively for n ? 7. 2010 Mathematics Subject Classifications. 05C12, 05C35, 05C90. .

In this paper, introducing a general modification of the classical Sz?sz-Mirakjan-Kantorovich (SMK) operators, we study their global approximation behavior. Some special cases are also presented. 2010 Mathematics Subject Classifications. 41A25, 41A36. .

In this paper, we derive some subordination and superordination results associated with the family of Jung-Kim-Srivastava integral operators defined on the space of meromorphic functions. Several sandwich-type results are also obtained. 2010 Mathematics Subject Classifications. Primary 30C45; Secondary 30C80. .

In this paper we study the Gilpin-Ayala competition system with random perturbation which is more general and more realistic than the classical Lotka-Volterra competition model. We verify that the positive solution of the system does not explode in a finite time. Furthermore, it is stochastically ultimately bounded and continuous a.s. We also obtain certain results about asymptotic behavior of the stochastic Gilpin-Ayala competition model. 2010 Mathematics Subject Classifications. 60H10, 34K50. .

The decay rate of the Gauss curvature of conformally flat planer surfaces of strictly negative curvature is studied. It is show that generically there is an asymptotic sequence that decays faster than quadratically in the distance from the origin. In the case that the conformal factor is of finite order, it is shown that one can improve this decay rate. 2010 Mathematics Subject Classifications. 53C21, 31A05. .

Let M be a separable compact Hausdorff space with dim M ? 2 and ? : M ? M be a homeomorphism with prime period p (p ? 2). Set M? = {x ( M|?(x) = x} = ( and M0 = M\M? . Suppose that M0 is dense in M and H2(M0/?, Z) ( 0, H2(?(M0/?), Z) ( 0. Let M' be another separable compact Hausdorff space with dim M' ? 2 and ?' be the self-homeomorphism of M' with prime period p. Suppose that M'0 = M'\M'?' is dense in M'. Then C(M) ? ?Zp ( C(M') ? ?'Zp if there is a homeomorphism F from M/? onto M'/?' such that F(M?) = M'?'. Thus, if (M, ?) and (M', ?') are orbit equivalent, then C(M) ? ?Zp ( C(M') ? ?'Zp. 2010 Mathematics Subject Classifications. 46L05. .
