About one algorithm of C2 interpolation using quartic splines [PDF]
The problem of C2 interpolation of a discrete set of data on the interval [a,b] representing the function f using quartic splines is investigated.

Convergence of Integro Quartic and Sextic B-Spline interpolation [PDF]
In this paper, quadratic and sextic B-splines are used to construct an approximating function based on the integral values instead of the function values at the knots.

Scalar correlation functions in de Sitter space from the stochastic spectral expansion [PDF]
We consider light scalar fields during inflation and show how the stochastic spectral expansion method can be used to calculate two-point correlation functions of an arbitrary local function of the field in de Sitter space.

We entertain the possibility that dark energy arises from the Higgs field of quintessence type in the non-perturbative regimes. For this purpose we utilize a set of exact solutions of Higgs field theory recently devised, in terms of Jacobi elliptical ...

Green Functions for the Wrong-Sign Quartic [PDF]
It has been shown that the Schwinger-Dyson equations for non-Hermitian theories implicitly include the Hilbert-space metric. Approximate Green functions for such theories may thus be obtained, without having to evaluate the metric explicitly, by truncation of the equations.

κ-Poincaré invariant orientable field theories at one-loop
We consider a family of κ-Poincaré invariant scalar field theories on 4-d κ-Minkowski space with quartic orientable interaction, that is for which ϕ and its conjugate ϕ † alternate in the quartic interaction, and whose kinetic operator is the square of a

Quartic AdS Interactions in Higher-Spin Gravity from Conformal Field Theory
Clarifying the locality properties of higher-spin gravity is a pressing task, but notoriously difficult due to the absence of a weakly-coupled flat regime. The simplest non-trivial case where this question can be addressed is the quartic self-interaction

Self-interacting multistate boson stars
In this paper, we consider rotating multistate boson stars with quartic self-interactions. In contrast to the nodeless quartic-boson stars in [1], the self-interacting multistate boson stars (SIMBSs) have two types of nodes, including the 1 S 2 S and 1 S
