      It is known that characters of irreducible representations of finite Lie algebras can be obtained using the Weyl character formula including Weyl group summations which make actual calculations almost impossible except for ...
    • On the class of harmonic mappings which is related to the class of bounded boundary rotation 

      Polatoğlu, Yaşar; Aydoğan, Melike; Kahramaner, Yasemin (Elsevier Science Inc, 360 Park Ave South, New York, Ny 10010-1710 Usa, 2015-09-15)
      The class of bounded radius of rotation is generalization of the convex functions. The concept of functions bounded boundary rotation originated from Loewner (1917). But he did not use the present terminology. It was Paatero ...
    • On the Direction Guidance in Structure Tensor Total Variation Based Denoising 

      Demircan-Tureyen, Ezgi (2019-07)
      This paper introduces a new analysis-based regularizer, which incor­ porates the neighborhood-awareness of the structure tensor total variation (STV) and the tunability of the directional total variation (DTV), in favor ...

      Erkut, Mehmet Hakan (Iop Publishing Ltd, Temple Circus, Temple Way, Bristol Bs1 6Be, England, 2011-12-10)
      We apply the global mode analysis, which has been recently developed for the modeling of kHz quasi-periodic oscillations (QPOs) from neutron stars, to the inner region of an accretion disk around a rotating black hole. ...
    • On the improvement of Mocanu's conditions 

      Nunokawa, M.; Owa, Shigeyoshi; Cho, N. E.; Sokół, J.; Yavuz Duman, Emel (Springer International Publishing, 2013-12)
      We estimate |Arg{p(z)}| for functions of the form p(z)=1+a1z+a2z2+a3z3+⋯ in the unit disc D={z:|z|<1} under several assumptions. By using Nunokawa’s lemma, we improve a few of Mocanu’s results obtained by differential ...
