Numerical approach for high precision 3-D relativistic star models [PDF]

, 1998
A multi-domain spectral method for computing very high precision 3-D stellar models is presented. The boundary of each domain is chosen in order to coincide with a physical discontinuity (e.g. the star's surface).

Entropic C-theorems in free and interacting two-dimensional field theories [PDF]

, 1998
The relative entropy in two-dimensional field theory is studied on a cylinder geometry, interpreted as finite-temperature field theory. The width of the cylinder provides an infrared scale that allows us to define a dimensionless relative entropy ...

Some Properties on Normalized Tails of Maclaurin Power Series Expansion of Exponential Function

Symmetry
In the paper, (1) in view of a general formula for any derivative of the quotient of two differentiable functions, (2) with the aid of a monotonicity rule for the quotient of two power series, (3) in light of the logarithmic convexity of an elementary function involving the exponential function, (4) with the help of an integral representation for the ...

Explicit formulas for partial Bell polynomials, Maclaurin's series expansions of real powers of inverse (hyperbolic) cosine and sine, and series representations of powers of Pi

, 2021
Abstract In the paper, by means of the Faa di Bruno formula, with the help of explicit formulas for special values of partial Bell polynomials with respect to two specific sequences generated by derivatives at the origin of the inverse sine or inverse cosine, and by virtue of two combinatorial identities containing the Stirling numbers of the ...

Slowly Rotating Homogeneous Stars and the Heun Equation [PDF]

, 2007
The scheme developed by Hartle for describing slowly rotating bodies in 1967 was applied to the simple model of constant density by Chandrasekhar and Miller in 1974. The pivotal equation one has to solve turns out to be one of Heun's equations.
