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 ... -
Some results on generalized toeplitz operator on generalized hardy space
(Işık University Press, 2016)In this paper, we define and study some properties of the generalized Hardy space HF,2, where F is an injective linear transform from Lp (?) into Lp (?) and ? is the unit circle in the complex plane C. Also we introduce ... -
