Exact solution of the Faddeev-Volkov model [PDF]

, 2007
The Faddeev-Volkov model is an Ising-type lattice model with positive Boltzmann weights where the spin variables take continuous values on the real line.

Graham's number stable digits: An exact solution [PDF]

Notes on Number Theory and Discrete Mathematics
In the decimal numeral system, we prove that the well-known Graham's number, G:=ⁿ3 (i.e., 3^{3^{...^{3}}} (n times)), and any base 3 tetration whose hyperexponent is larger than n share the same slog₃(G)-1 rightmost digits (where slog indicates the ...

Exact solution of the Φ23 finite matrix model

Nuclear Physics B, 2022
We find the exact solutions of the Φ23 finite matrix model (Grosse-Wulkenhaar model). In the Φ23 finite matrix model, multipoint correlation functions are expressed as G|a11…aN11|…|a1B…aNBB|.

Exact Solution and Exotic Fluid in Cosmology

Entropy, 2012
We investigate cosmological consequences of nonlinear sigma model coupled with a cosmological fluid which satisfies the continuity equation. The target space action is of the de Sitter type and is composed of four scalar fields.

Exact solution of the two-axis countertwisting Hamiltonian [PDF]

, 2016
It is shown that the two-axis countertwisting Hamiltonian is exactly solvable when the quantum number of the total angular momentum of the system is an integer after the Jordan-Schwinger (differential) boson realization of the SU(2) algebra.

Insight on the Nonhomogeneous Pantograph Equation with an Arbitrary Polynomial of Degree n: Explicit Solution

Mathematics
This paper solves a nonhomogeneous version of the pantograph equation. The nonhomogeneous term is taken as a polynomial of degree n with arbitrary coefficients.

Another exact inflationary solution

, 2000
A new closed-form inflationary solution is given for a hyperbolic interaction potential. The method used to arrive at this solution is outlined as it appears possible to generate additional sets of equations which satisfy the model.

Exact Static Cylindrical Solution to Conformal Weyl Gravity [PDF]

, 2012
We present the exact exterior solution for a static and neutral cylindrically symmetric source in locally conformal invariant Weyl gravity. As a special case the general relativity analogue still can be attained, however only as a sub-family of solutions.
