    • Mackey group categories and their simple functors 

      Yaylıoğlu, Volkan Dağhan (Bilkent University, 2012)
      Constructing the Mackey group category M using axioms which are reminiscent of fusion systems, the simple RM-functors (the simple functors from the R-linear extension of M to R-modules, where R is a commutative ring) can ...
    • Management skills training needs analysis of company and battalion commanders in the Turkish army 

      Meydan, Cem Harun (Bilkent University, 2001)
      The Turkish Army like other organizations tries to keep up with the change in all areas and uses some methods of change. One of the areas is management and the method of change used by The Army is training and development ...
    • A measure disintegration approach to spectral multiplicity for normal operators 

      Ay, Serdar (Bilkent University, 2012)
      In this thesis we studied the notion of direct integral Hilbert spaces, first introduced by J. von Neumann, and the closely related notion of decomposable operators, as defined in Kadison and Ringrose [1997] and Abrahamse ...
    • Minimal surfaces on three-dimensional Walker manifolds 

      Berani, Erzana (Bilkent University, 2017-06)
      Lorentzian Geometry has shown to be very useful in a wide range of studies including many diverse research elds, especially in the theory of general relativity and mathematical cosmology. A Walker manifold descends from ...
    • Modular representations and monomial burnside rings 

      Coşkun, Olcay (Bilkent University, 2004)
      We introduce canonical induction formulae for some character rings of a finite group, some of which follows from the formula for the complex character ring constructed by Boltje. The rings we will investigate are the ...
    • The Monge-Kantorovich mass transportation problem 

      Demirel, İhsan (Bilkent University, 2017-09)
      The Monge mass transportation problem was stated by French Mathematician, G. Monge [6]. After that Soviet Mathematician Leonid Kantorovich [4] published a relaxed version of the problem, namely the Monge-Kantorovich ...
    • The monomial Burnside functor 

      Okay, Cihan (Bilkent University, 2009)
      Given a finite group G, we can realize the permutation modules by the linearization map defined from the Burnside ring B(G) to the character ring of G, denoted AK(G). But not all KG-modules are permutation modules. To ...
    • Monomial Gotzmann sets 

      Pir, Ata Fırat (Bilkent University, 2011)
      A homogeneous set of monomials in a quotient of the polynomial ring S := F[x1, . . . , xn] is called Gotzmann if the size of this set grows minimally when multiplied with the variables. We note that Gotzmann sets in the ...
    • N-tangle Kanenobu knots with the same Jones polynomials 

      Kutluay, Deniz (Bilkent University, 2010)
      It is still an open question if there exists a non-trivial knot whose Jones polynomial is trivial. One way of attacking this problem is to develop a mutation on knots which keeps the Jones polynomial unchanged yet alters ...
    • Non-stationary Markov chains 

      Mallak, Saed (Bilkent University, 1996)
      In thi.s work, we studierl the Ergodicilv of Non-Stationary .Markov chains. We gave several e.xainples with different cases. We proved that given a sec[uence of Markov chains such that the limit of this sec|uence is an ...
    • Numerical study of orthogonal polynomials for fractal measures 

      Şimşek, Ahmet Nihat (Bilkent University, 2016-07)
      In recent years, potential theory has an essential effect on approximation theory and orthogonal polynomials. Basic concepts of the modern theory of general orthogonal polynomials are described in terms of Potential Theory. ...
    • On Arf rings 

      Arslan, Sefa Feza (Bilkent University, 1994)
      In this thesis, we worked with curves which have cusp type singularities. We described the Arf theory, which solves the problem of understanding and finding the multiplicity sequence of a curve branch algebraically. We ...
    • On complete intersections and connectedness 

      Önal, Meltem (Bilkent University, 2002)
      In this thesis, we study the relation between connectedness and complete intersections. We describe the concept of connectedness in codimension k. We also study the basic facts about Cohen-Macaulay rings, and give ...
    • On Gambler's ruin problem in some models 

      Sevim, Çiğdem (Bilkent University, 2005)
      2-player probability games is an important subject of probability theory. In this thesis, we considered four different two-player probability games. We calculated the expected value of stopping times of the games. Since ...
    • On lower bounds of character sums 

      Özbudak, Ferruh (Bilkent University, 1995)

    • On lower degree bounds for vector invariants over finite fields 

      Madran, Uğur (Bilkent University, 2000)
      The purpose of this thesis is to obtain a lower degree bound in modular invariant theory for a special case. More precisely, let G be any group and k be a finite field of positive characteristic p such that p divides |G| ...
    • On monomial Burnside rings 

      Yaraneri, Ergün (Bilkent University, 2003)
      This thesis is concerned with some different aspects of the monomial Burnside rings, including an extensive, self contained introduction of the A−fibred G−sets, and the monomial Burnside rings. However, this work has two ...
    • On possible deterioration of smoothness under the operation of convolution 

      Uludağ, A Muhammed (Bilkent University, 1996)
      We show that the convolution of two probability densities which are restrictions to R of entire functions can possess infinite essential supremuin on each interval. We also present several sufficient conditions of ...
    • On power series with one singular point at circumference of convergence 

      Yardımcı, Umut (Bilkent University, 2002)
      We obtain two refinements of Faber’s theorem related to power series with one singular point at circumference of convergence. The first one characterizes growth at the singular point in more precise scale of growth. The ...
