Anamorphic Quasiperiodic Universes in Modified and Einstein Gravity with Loop Quantum Gravity Corrections
Marcelo M. Amaral, Raymond Aschheim, Laurenţiu Bubuianu +3
The goal of this work is to elaborate on new geometric methods of constructing exact and parametric quasiperiodic solutions for anamorphic cosmology models in modified gravity theo…
Starobinsky Inflation and Dark Energy and Dark Matter Effects from Quasicrystal Like Spacetime Structures
R. Aschheim, L. Bubuianu, Fang Fang +3
The goal of this work on mathematical cosmology and geometric methods in modified gravity theories, MGTs, is to investigate Starobinsky-like inflation scenarios determined by gravi…
Heterotic Supergravity with Internal Almost-Kähler Spaces, Instantons for , or , Gauge Groups, and Deformed Black Holes with Soliton, Quasiperiodic and/or Pattern-forming Structures
Laurenţiu Bubuianu, Klee Irwin, Sergiu I. Vacaru
Heterotic supergravity with (1+3)--dimensional domain wall configurations and (warped) internal, six dimensional, almost-Kähler manifolds are studied. Considering…
Cosmological Attractors and Anisotropies in Two Measure Theories, Effective EYMH systems, and Off--Diagonal Inflation Models
Subhash Rajpoot, Sergiu I. Vacaru
Applying the anholonomic frame deformation method, we construct various classes of cosmological solutions for effective Einstein -- Yang-Mills -- Higgs, and two measure theories. T…
Off-Diagonal Deformations of Kerr Metrics and Black Ellipsoids in Heterotic Supergravity
Sergiu I. Vacaru, Klee Irwin
Geometric methods for constructing exact solutions of motion equations with first order corrections to the heterotic supergravity action implying a non-trivial Yang-Mi…
