Flat Galactic Rotation Curves from Geometry in Weyl Gravity
Cemsinan Deliduman, Oguzhan Kasikci, Baris Yapiskan
We searched for a resolution of the flat galactic rotation curve problem from geometry instead of assuming the existence of dark matter. We observed that the scale independence of…
Absence of Relativistic Stars in f(T) Gravity
Cemsinan Deliduman, Baris Yapiskan
In this work we investigate the structure of neutron stars in modified f(T) gravity models. We find that, unlike the f(R) models, the equations of motion put a rather strict constr…
Seiberg--Witten Maps to All Orders
Kayhan Ulker, Baris Yapiskan
All order Seiberg--Witten maps of gauge parameter, gauge field and matter fields are given as a closed recursive formula. These maps are obtained by analyzing the order by order so…
Equivalence of partition functions for noncommutative U(1) gauge theory and its dual in phase space
O. F. Dayi, B. Yapiskan
Equivalence of partition functions for U(1) gauge theory and its dual in appropriate phase spaces is established in terms of constrained hamiltonian formalism of their parent actio…
Duals of noncommutative supersymmetric U(1) gauge theory
O. F. Dayi, K. Ulker, B. Yapiskan
Parent actions for component fields are utilized to derive the dual of supersymmetric U(1) gauge theory in 4 dimensions. Generalization of the Seiberg-Witten map to the component f…
Properties of Solutions in 2+1 Dimensions
M. Hortacsu, H. T. Ozcelik, B. Yapiskan
We solve the Einstein equations for the 2+1 dimensions with and without scalar fields. We calculate the entropy, Hawking temperature and the emission probabilities for these cases.…
