Induced Matter Theory of gravity from a Weitzenböck 5D vacuum and pre-big bang collapse of the universe
(Springer, 2013-02)
We extend the Induced Matter Theory of gravity (IMT) to 5D curved spacetimes by using the Weitzenböck representation of connections on a 5D curved spacetime. In this representation the 5D curvature tensor becomes null, so ...
Extended geometry and gauged maximal supergravity
(Springer, 2013-06-11)
We consider generalized diffeomorphisms on an extended mega-space associated to the U-duality group of gauged maximal supergravity in four dimensions, E7(7). Through the bein for the extended metric we derive dynamical ...
Tinkertoys for the E-6 theory
(Springer, 2015-09-01)
Compactifying the 6-dimensional (2,0) superconformal field theory, of type ADE, on a Riemann surface, C, with codimension-2 defect operators at points on C, yields a 4-dimensional N = 2 superconformal field theory. An ...
Minimally generated abstract logics
(2009)
In this paper we study an alternative approach to the concept of abstract logic and to connectives in abstract logics. The notion of abstract logic was introduced by Brown and Suszko (Diss Math 102:9–42, 1973)—nevertheless, ...
Heterotic α´-corrections in Double Field Theory
(Springer, 2014-12)
We extend the generalized flux formulation of Double Field Theory to include all the first order bosonic contributions to the α′ expansion of the heterotic string low energy effective theory. The generalized tangent space ...
Can the dark matter annihilation signal be significantly boosted by substructures?
(IOP Publishing, 2016)
A very general cosmological consideration suggests that, along with galactic dark
matter halos, much smaller dark matter structures may exist. These structures are usually
called ‘clumps’, and their mass extends to 10−6M⊙ ...
Nonlinear Dynamics for the prediction of Statistical Distributions: An Operational Research perspective
(2013)
A semantic connection between nonlinear or linear dynamical systems and statistical Gaussian distributions is developed as a theory. This connection is applied to predict changes in the Gaussian distribution when models ...
Heterotic α' corrections in Double Field Theory
(Springer, 2014-12-10)
We extend the generalized flux formulation of Double Field Theory to include all the first order bosonic contributions to the α´ expansion of the heterotic string low energy effective theory. The generalized tangent space ...
L ∞ algebras and tensor hierarchies in Exceptional Field Theory and Gauged Supergravity
(Springer, 2019-01)
We show how the gauge and field structure of the tensor hierarchies in Double and E7(7) Exceptional Field Theory fits into L∞ algebras. Special attention is paid to redefinitions, the role of covariantly constrained fields ...
