Antimagic labeling of the union of subdivided stars
(Işık University Press, 2016-02-22)Enomoto et al. (1998) defined the concept of a super (a, 0)-edge-antimagic total labeling and proposed the conjecture that every tree is a super (a, 0)-edge-antimagic total labeling. In support of this conjecture, the ... -
Existence and uniqueness of tripled fixed points for mixed monotone operators with perturbations and application
(Işık University Press, 2016)In this article, we get the existence and uniqueness of tripled fixed points without assuming the operator to be compact or continuous, which extends the existing corresponding results. As applications, we utilize the ... -
A weighted goal programming approach to fuzzy linear regression with quasi type-2 fuzzy input-output data
(Işık University Press, 2016)This study attempts to develop a regression model when both input data and output data are quasi type-2 fuzzy numbers. To estimate the crisp parameters of the regression model, a linear programming model is proposed based ... -
