    • The pandemic fusion system for endomorphism algebras of p-permutation modules 

      Nika, Andi (Bilkent University, 2018-09)
      During the 1980's Puig developed a new approach to modular representation theory, introducing new p-local invariants and thereby extending Green's work on G-algebras. We investigate the Puig category, commenting on its ...

    • Plane sextics with a type E7 singular point 

      Aktaş, Mehmet Emin (Bilkent University, 2011)
      The computation of the fundamental grup of a plane sextic (i.e., curves B ⊂ P 2 ) still remain unanswered problem. There is an huge effort on this subject. In this thesis, we study plane sextic curves with a type E7 ...
    • Projective resolutions over EI-categories 

      Bahran, Cihan (Bilkent University, 2012)
      Representations of EI-categories occur naturally in algebraic K-theory and algebraic topology (see [4], [10], [12]). In this thesis, we study EI-category representations with finite projective dimension. We apply this ...
    • Ramanujan's congruences for the partition function 

      Aygin, Zafer Selçuk (Bilkent University, 2009)
      In this thesis, we study Ramanujan’s congruences for the partition function and some of their combinatorial interpretations. Our main tools are from the theory of theta function.
    • Real monomial Burnside rings and a decomposition of the the tom Dieck map 

      Tuvay, İpek (Bilkent University, 2009)
      This thesis is mainly concerned with a decomposition of the reduced tom Dieck map die : f A(RG) → B(G) × into two maps die+ and die− of the real monomial Burnside ring. The key idea is to introduce a real Lefschetz ...
    • Recursion operators and classification of integrable nonlinear equations 

      Bilen, Ergün (Bilkent University, 2012)
      Recursion operators, if they exist, of nonlinear partial differential equations map symmetries to symmetries of these equations. It is this property that the integrable nonlinear partial differential equations possess ...
    • Regular basis and functor Ext 

      Ertuğrul, Zehra (Bilkent University, 1994)
      This work is a study of the relation between the vanishing of Ext functor and the existence of regular bases in the cartesian product and tensor product of some special Kothe spaces. We give some new results concerning ...
    • Representations of symmetric groups and structures of Lie algebra 

      Acar, Merve (Bilkent University, 2017-08)
      The aim of this thesis construct structure of Free Lie Algebra L(V ) generated by nite dimensional vector space V and decompose into irreducible components of a given degree n. To splits into irreducible component, ...
    • Reproducing kernel Hilbert spaces 

      Okutmuştur, Baver (Bilkent University, 2005)
      In this thesis we make a survey of the theory of reproducing kernel Hilbert spaces associated with positive definite kernels and we illustrate their applications for interpolation problems of Nevanlinna-Pick type. Firstly ...
    • Review of an approach to obstruction theory 

      Kırdar, Mehmet (Bilkent University, 1994)
      In this work, we summarized an approach to obstruction tlieory developed by E. Thomas. We gave some illustrative examples to demonstrate the method. These are : 2-plane fields on manifolds revi(iwing works of Thotnas, 3 ...
    • Riemann boundary value problem 

      Derya, Ayşe Mutlu (Bilkent University, 2000)
    • Schlesinger transformations of second discrete painleve equation 

      Yurtseven, Özden (Bilkent University, 2004)
    • Schubert calculus, adjoint representation and moment polytopes 

      Sakar, Serkan (Bilkent University, 2012)
      Let Hν denote the irreducible representation of the special unitary group SU(n) corresponding to Young diagram ν and let g = su(n) denote the Lie algebra of SU(n). One can show that Hν appears in the symmetric algebra ...
    • Sectional curvature of standard static space-times 

      Yavuz, Bengi Ruken (Bilkent University, 2013)
      Curvature related geometric properties of warped product manifolds are given. The casual structure of Lorentzian warped products is reviewed. In particular, two well-known examples of warped product space-times models, ...
    • Simple functors of admissible linear categories 

      Demirel, Merve (Bilkent University, 2013)
      We review the notion of an admissible R-linear category for a commutative unital ring R and we prove the classification theorem for simple functors of such a category by Barker-Boltje which states that there is a bijective ...
    • Singularities of plane model of the modular curve Yo(l) 

      Kara, Orhun (Bilkent University, 1998)
    • Smoothness of the green function for some special compact sets 

      Çelik, Serkan (Bilkent University, 2010)
      Smoothness of the Green functions for some special compact sets, which are sequences of closed intervals with certain parameters, is described in terms of the function ϕ(δ) = 1 log 1 δ that gives the logarithmic measure ...
    • Smoothness properties of Green's functions 

      Türkün, Can (Bilkent University, 2014)
      Basic notions of potential theory are explained with illustrative examples. Many important properties, including the characteristic ones, of Green’s functions that are defined by the help of equilibrium measures are ...
    • Some criteria of selfadjointness for unbounded operators in Hilbert spaces 

      Özkaraca, Mustafa İsmail (Bilkent University, 2013)
      This is a detailed presentation of some criteria of selfadjointness for unbounded operators in a Hilbert space, through operator Cauchy problems. We also include detailed preliminary results on unbounded linear operators ...
