Liftable homeomorphisms of cyclic and rank two finite abelian branched covers over the real projective plane Atalan, Ferihe; Medetogullari, Elif; Ozan, Yıldıray (Elsevier BV, 2021-02-01) © 2020 Elsevier B.V.In this note, we investigate the property for regular branched finite abelian covers of the real projective plane, where each homeomorphism of the base (preserving the branch locus) lifts to a homeomorp...
Liftable homeomorphisms of rank two finite abelian branched covers Atalan, Ferihe; Medetogullari, Elif; Ozan, Yıldıray (2020-11-01) We investigate branched regular finite abelian A-covers of the 2-sphere, where every homeomorphism of the base (preserving the branch locus) lifts to a homeomorphism of the covering surface. In this study, we prove that if...

Self-dual metrics on non-simply connected 4-manifolds Kalafat, Mustafa; Ozan, Yıldıray; Arguez, Hulya (2013-02-01) We construct self-dual (SD) but not locally conformally flat (LCF) metrics on families of non-simply connected 4-manifolds with small signature. We construct various sequences with bounded or unbounded Betti numbers and Eu...
Learner modeling to facilitate personalized e-Learning experience Görgün, Ilhami; Türker, Ali; Ozan, Yıldıray; Heller, Jürgen (2005-12-01) This article describes a learner modeling strategy that is employed by an adaptive learning system in order to provide each learner with a personalized e-Learning experience. Parameters related to the learners' prior knowl...
Relative flux homomorphism in symplectic geometry Ozan, Yıldıray (American Mathematical Society (AMS), 2005-01-01) In this work we define a relative version of the flux homomorphism, introduced by Calabi in 1969, for a symplectic manifold. We use it to study ( the universal cover of) the group of symplectomorphisms of a symplectic mani...

Relative topology of real algebraic varieties in their complexifications Ozan, Yıldıray (Mathematical Sciences Publishers, 2004-12-01) We investigate, for a given smooth closed manifold M, the existence of an algebraic model X for M (i.e., a nonsingular real algebraic variety diffeomorphic to M) such that some nonsingular projective complexification i:X--...
