Every norm is a restriction of an orderunit norm
Çağlar, Mert; Ercan, Zafer (Scientific Technical Research Council TurkeyTUBİTAK, Ataturk Bulvarı No 221, Kavaklıdere, Tr06100 Ankara, Turkey, 2016)We point out the equivalence of the fact that every norm on a vector space is a restriction of an orderunit norm to that of Paulsen's construction concerning generalization of operator systems. 
Generalized Alexandroff Duplicates and CD 0(K) spaces
Çağlar, Mert; Ercan, Zafer; Polat, Faruk (2006)We define and investigateCD Σ,Γ(K, E)type spaces, which generalizeCD 0type Banach lattices introduced in [1]. We state that the space CD Σ,Γ(K, E) can be represented as the space of Evalued continuous functions on the ... 
Inequalities for the Schwarzian derivative for subclasses of convex functions in the unit disc
Çağlar, Mert; Polatoğlu, Yaşar; Şen, Arzu (2006)Nehari norm of the Schwarzian derivative of an analytic function is closely related to its univalence. The famous NehariKraus theorem ((3), (4)) and AhlforsW eill theorem (1) are of fundamental importance in this direction. ... 
Invariant Subspaces of Weakly Compactfriendly Operators
Çağlar, Mert; Mısırlıoğlu, Tunç (Scientific Technical Research Council TurkeyTubitak, Ataturk Bulvari No 221, Kavaklidere, Tr06100 Ankara, Turkey, 2012)We prove that if a nonzero weakly compactfriendly operator B on a Banach lattice with topologically full center is locally quasinilpotent, then the super rightcommutant [B > of B has a nontrivial closed invariant ... 
Lambdafractional properties of generalized Janowski functions in the unit disc
Çağlar, Mert; Polatoğlu, Yaşar; Yavuz, Emel (2008)For analytic function f(z) = z + a2z 2 + · · · in the open unit disc D, a new fractional operator Dλf(z) is defined. Applying this fractional operator Dλf(z) and the principle of subordination, we give new proofs for ... 
Multivalued starlike functions of complex order
Polatoğlu, Yaşar; Çağlar, Mert; Owa, Shigeyoshi; Yavuz, Emel; Şen, Arzu (2008)Let Aα be the class of functions f(z) = z α (z + a2z 2 + · · ·) which are analytic in the open unit disc U. For f(z) ∈ Aα using the fractional calculus, a subclass S ∗ α (1−b) which is the class of starlike functions ... 
On Janowski starlike functions
Çağlar, Mert; Polatoğlu, Yaşar; Şen, A.; Yavuz, Emel; Owa, Shigeyoshi (Springer International Publishing Ag, Gewerbestrasse 11, Cham, Ch6330, Switzerland, 2007)For analytic functions f(z) in the open unit disc U with f(0) = 0 and f'(0) = 1, applying the fractional calculus for f(z), a new fractional operator Dlambda f(z) is introduced. Further, a new subclass Flambda(*)(A, B) ... 
On positive operators without invariant sublattices
Çağlar, Mert; Gönülli, Uğur; Mısırlıoğlu, Remzi Tunç (2009)By slightly modifying some of the examples given in [6], we obtain further examples of positive operators on the discrete Banach lattices c0, c, and `p (1 ≤ p < ∞) without nontrivial closed invariant sublattices. 
Orderunitmetric spaces
Çağlar, Mert; Ercan, Zafer (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 201409)We study the concept of cone metric space in the context of ordered vector spaces by setting up a general and natural framework for it.

Coşkun, Merve; Polat, Özgür; Coşkun, Fatih Mehmet; Durmuş, Zehra; Çağlar, Müjdat; Turut, Abdulmecit (Royal Soc Chemistry, Thomas Graham House, Science Park, Milton Rd, Cambridge Cb4 0Wf, Cambs, England, 2018)We have prepared LaCrO3 (LCO) and 10% Ir doped LCO samples by the solid state reaction method and studied the electrical modulus and the other dielectric properties of the samples by means of the impedance spectroscopy in ... 
The higher order Schwarzian derivative: Its applications for chaotic behavior and new invariant sufficient condition of chaos
Hacıbekiroğlu, Gürsel; Çağlar, Mert; Polatoğlu, Yaşar (Elsevier, 200906)The Schwarzian derivative of a function which is defined in the interval having higher order derivatives is given by A sufficient condition for a function to behave chaotically is that its Schwarzian derivative is ...
