Locally Conformal Analysis of Non-Degenerate Odd Pairs

Begüm Ateşli, Aybike Çatal-Özer, Oğul Esen

We study the locally conformal geometry of cosymplectic and coorientable contact manifolds within a common algebraic framework based on a non-degenerate odd pair: a one-form and a…

Stability Analysis of the Cosmological Dynamics of -complete Stringy Gravity

A. Savaş Arapoğlu, Sermet Çağan, Aybike Çatal-Özer

The massless fields in the universal NS-NS sector of string theory form multiplets of Double Field Theory, which is a theory that provides a T-duality covariant formulati…

Drinfel'd Double of Bialgebroids for String and M Theories: Dual Calculus Framework

Aybike Çatal-Özer, Keremcan Doğan, Cem Yetişmişoğlu

We extend the notion of Lie bialgebroids for more general bracket structures used in string and M theories. We formalize the notions of calculus and dual calculi on algebroids. We…

Generalized 11D supergravity equations from tri-vector deformations

Ilya Bakhmatov, Aybike Çatal-Özer, Nihat Sadik Deger +2

In arXiv:2203.03372 we presented a modification of 11-dimensional supergravity field equations which upon dimensional reduction yields generalized supergravity equations in 10-dime…

Massive Deformations of Type IIA Theory Within Double Field Theory

Aybike Catal-Ozer

We obtain massive deformations of Type IIA supergravity theory through duality twisted reductions of Double Field Theory (DFT) of massless Type II strings. The mass deformation is…

A Massive S-duality in 4 dimensions

Aybike Catal-Ozer, Cemsinan Deliduman, Ulas Saka

We reduce the Type IIA supergravity theory with a generalized Scherk-Schwarz ansatz that exploits the scaling symmetry of the dilaton, the metric and the NS 2-form field. The resul…

Beta, Dipole and Noncommutative Deformations of M-theory Backgrounds with One or More Parameters

Aybike Catal-Ozer, Nihat Sadik Deger

We construct new M-theory solutions starting from those that contain 5 U(1) isometries. We do this by reducing along one of the 5-torus directions, then T-dualizing via the action…

Non-commutative Geometry and the Higgs Masses

A. Catal, T. Dereli

We study a non-commutative generalization of the standard electroweak model proposed by Balakrishna, Gursey and Wali [ Phys.Lett. B254(1991)430] that is formulated in terms of the…
