Hyperbolic inflation is an extension of the slow-roll inflation in multi-field models. We extend hyperbolic inflation by adding a gauge field and find four-type attractor solutions: slow-roll inflation, hyperbolic inflation, anisotropic slow roll inflation, and anisotropic hyperbolic inflation. We perform the stability analysis with the dynamical system method. We also study the transition behaviors of solutions between anisotropic slow roll inflation and anisotropic hyperbolic inflation. Our… Expand
Anisotropic hyperbolic inflation for a model of two scalar and two vector fields
In this paper, we extend a recent proposed model of two scalar and two vector fields to a hyperbolic inflation scenario, in which the field space of two scalar fields is a hyperbolic space instead ofExpand

Hyperbolic Inflation.
A model of cosmological inflation is proposed in which field space is a hyperbolic plane. The inflaton never slow-rolls, and instead orbits the bottom of the potential, buoyed by a centrifugal force.Expand
Anisotropic inflation in Gauss-Bonnet gravity
We study anisotropic inflation with Gauss-Bonnet correction in presence of a massless vector field. In this scenario, exact anisotropic power-law inflation is realized when the inflaton potential,Expand
Anisotropic constant-roll Inflation
We study constant-roll inflation in the presence of a gauge field coupled to an inflaton. By imposing the constant anisotropy condition, we find new exact anisotropic constant-roll inflationaryExpand
Statistical anisotropy from anisotropic inflation
We review an inflationary scenario with the anisotropic expansion rate. An anisotropic inflationary universe can be realized by a vector field coupled with an inflaton, which can be regarded as aExpand
Inflation with Multi-Vector-Hair: The Fate of Anisotropy
We study inflation with multiple vector fields. In the presence of non-trivial couplings between the inflaton and the vector fields, it turns out that no-hair?conjecture does not hold and vector hairExpand
Anisotropic inflation with non-abelian gauge kinetic function
We study an anisotropic inflation model with a gauge kinetic function for a non-abelian gauge field. We find that, in contrast to abelian models, the anisotropy can be either a prolate or an oblateExpand
Anisotropic Power-law Inflation:A counter example to the cosmic no-hair conjecture
It is widely believed that anisotropy in the expansion of the universe will decay exponentially fast during inflation. This is often referred to as the cosmic no-hair conjecture. However, we find aExpand
Inflationary universe with anisotropic hair.
A universal relation between the anisotropy and a slow-roll parameter of inflation is found and has observational implications and gives a counterexample to the cosmic no-hair conjecture. Expand
Anisotropic power-law inflation
We study an inflationary scenario in supergravity model with a gauge kinetic function. We find exact anisotropic power-law inflationary solutions when both the potential function for an inflaton andExpand
Designing Anisotropic Inflation with Form Fields
We study inflation with anisotropic hair induced by form fields. In four dimensions, the relevant form fields are gauge (one-form) fields and two-form fields. Assuming the exponential form ofExpand
