nTuplet coincidence point theorems in partially ordered probabilistic metric spaces
(Hindawi Ltd, 2018)In this paper, we investigate existence of ntuplet coincidence point theorems in partially ordered probabilistic metric spaces. Also, we gave uniqueness of ntuplet fixed point theorems in this space. 
Network synchronization: Spectral versus statistical properties
(Elsevier B.V, 200612)We consider synchronization of weighted networks, possibly with asymmetrical connections. Focusing on causal relations rather than the observed correlations, we show that the synchronizability of networks cannot be directly ... 
A new form of Kakutani fixed point theorem and intersection theorem with applications
(Ministry Communications & High Technologies, 2021)The first aim of this paper is to extend the Kakutani's fixed point theorem from locally convex topological vector spaces to linear topological spaces. The second goal is to present sufficient conditions under which the ... 
A new theory of complex rays
(Oxford Univ Press, 200412)A new approach to the theory of complex rays is presented. It is shown that the threedimensional Minkowski space, the variant of the well known fourdimensional spacetime Minkowski space of the special theory of relativity, ... 
Nonexistence and existence of localized solitary waves for the twodimensional longwaveshortwave interaction equations
(Elsevier Ltd, 201004)In this study, we establish the nonexistence and existence results for the localized solitary waves of the twodimensional longwaveshortwave interaction equations. Both the nonexistence and existence results are based ... 
Nonlinear waves in a fluidfilled inhomogeneous elastic tube with variable radius
