Holography, the Cosmological Constant and the Upper Limit of the Number of e-foldings
If the source of the current accelerating expansion of the universe is a positive cosmological constant, Banks and Fischler argued that there exists an upper limit of the total number of e-foldings of inflation. We further elaborate on the upper limit in the senses of viewing the cosmological horizon as the boundary of a cavity and of the holographic Dbound in a de Sitter space. Assuming a simp...
متن کاملAn upper bound on the number of e-foldings
If the present acceleration of the universe is due to an asymptotically de Sitter universe with small cosmological constant, and the principle of Cosmological Complementarity is valid, then the number of e-foldings during inflation is bounded.

On the Computation of Foldings
The process of determining the development (or net) of a polyhedron or of a developable surface is called unfolding and has a unique result, apart from the placement of different components in the plane. The reverse process called folding is much more complex. In the case of polyhedra it leads to a system of algebraic equations. A given development can correspond to several or even to infinitel...
متن کاملUpper limit on the number of bound states of the spinless Salpeter equation
We obtain, using the Birman-Schwinger method, upper limits on the total number of bound states and on the number of l-wave bound states of the semirelativistic spinless Salpeter equation. We also obtain a simple condition, in the ultrarelativistic case (m = 0), for the existence of at least one l-wave bound states: C(l, p/(p− 1)) ∫∞ 0 dr r p−1 |V −(r)|p ≥ 1, where C(l, p/(p− 1)) is a known func...
