    • Every norm is a restriction of an order-unit norm 

      Çağlar, Mert; Ercan, Zafer (Scientific Technical Research Council Turkey-TUBİTAK, Ataturk Bulvarı No 221, Kavaklıdere, Tr-06100 Ankara, Turkey, 2016)
      We point out the equivalence of the fact that every norm on a vector space is a restriction of an order-unit 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 0-type Banach lattices introduced in [1]. We state that the space CD Σ,Γ(K, E) can be represented as the space of E-valued 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 Compact-friendly Operators 

      Çağlar, Mert; Mısırlıoğlu, Tunç (Scientific Technical Research Council Turkey-Tubitak, Ataturk Bulvari No 221, Kavaklidere, Tr-06100 Ankara, Turkey, 2012)
      We prove that if a non-zero weakly compact-friendly operator B on a Banach lattice with topologically full center is locally quasi-nilpotent, then the super right-commutant [B > of B has a non-trivial closed invariant ...
    • Lambda-fractional 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, Ch-6330, 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 D-lambda f(z) is introduced. Further, a new subclass F-lambda(*)(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 non-trivial closed invariant sublattices.
    • Order-unit-metric spaces 

      Çağlar, Mert; Ercan, Zafer (Springer, Van Godewijckstraat 30, 3311 Gz Dordrecht, Netherlands, 2014-09)
      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.
    • Positive Operators on Hilbert Lattices 

      Mısırlıoğlu, Remzi Tunç; Çağlar, Mert; Çavuşoğlu, Özlem (International Conference on Theory and Applications of Mathematics and Informatics, ICTAMI, 2009)

      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, 2009-06)
      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 ...
