    • 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.
    • 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 ...
    • 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.
    • The electrical modulus and other dielectric properties by the impedance spectroscopy of LaCrO3 and LaCr0.90Ir0.10O3 perovskites 

      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 ...
    • λ-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 ...
