    • Torus Knots and Contact Surgeries 

      Saraç, İrem Özge (Fen Bilimleri Enstitüsü, 2018)
      A closed curve homeomorphic to the unit circle in a 3-manifold is called a knot. In particularly, a knot that can be drawn on a torus without intersecting itself is called a torus knot. In this thesis, we study torus knots ...

    • A Study On Direct Summand Submodules Over Noncommutative Rings 

      Altun Özarslan , Meltem (Fen Bilimleri Enstitüsü, 2018)
      A natural problem to consider in ring and module theory is to investigate the cancellation property of a given object. This problem was first considered by Jónsson and Tarski for any algebraic system and then gave rise ...
