Curves on surfaces with prescribed pairwise intersection numbers
Ferit Öztürk
Given an ordered sequence of -choose-2 integers, we give necessary and sufficient conditions to have an ordered collection of simple closed curves on a torus such that the a…
An exotic 5RP^2 in the 4-sphere
Gordana Matić, Ferit Öztürk, Javier Reyes +2
We show an example of an embedded copy of 5RP^2 in the four-sphere which is topologically standard but smoothly knotted, i.e. smoothly not isotopic to the standard embedding.
Real algebraic overtwisted contact structures on 3-spheres
Şeyma Karadereli, Ferit Öztürk
A real algebraic link in the 3-sphere is defined as the zero locus in the 3-sphere of a real algebraic function from to . A real algebraic open book de…
Real tight contact structures on lens spaces and surface singularities
Sinem Onaran, Ferit Öztürk
We classify the real tight contact structures on solid tori up to equivariant contact isotopy and apply the results to the classification of real tight structures on and real…
Morse-Bott functions on orthogonal groups
H. Işıl Bozma, William D. Gillam, Ferit Öztürk
We make a detailed study of various (quadratic and linear) Morse-Bott trace functions on the orthogonal groups . We describe the critical loci of the quadratic trace function…
Contact Structures on AR-singularity links
Cagri Karakurt, Ferit Ozturk
An isolated complex surface singularity induces a canonical contact structure on its link. In this paper, we initiate the study of the existence problem of Stein cobordisms between…
A real open book not fillable by a real Lefschetz fibration
Ferit Ozturk, Nermin Salepci
A real 3- or 4-manifold has by definition an orientation preserving smooth involution acting on it. We consider Lefschetz fibrations of 4-dimensional manifolds-with-boundary and op…
Generalised Thurston-Bennequin invariants for real algebraic surface singularities
Ferit Ozturk
A generalised Thurston-Bennequin invariant for a Q-singularity of a real algebraic variety is defined as a linking form on the homologies of the real link of the singularity. The m…
