The Rate of Increase of Real Continuous Solutions of Certain Algebraic Functional Equations [PDF]

Transactions of the American Mathematical Society, 1959
In this equation, and throughout this paper, P(t, u, v) denotes a polynomial in the variables t, u, v, with real coefficients, and b(t) is a function which is positive and continuous for t greater than or equal to some positive number a. The results presented below generalize those of 0. E. Lancaster [4], and S. M.

Permanental Point Processes on Real Tori, Theta Functions and Monge–Ampère Equations [PDF]

Annales de la Faculté des sciences de Toulouse : Mathématiques, 2019
Inspired by constructions in complex geometry we introduce a thermodynamic framework for Monge–Ampère equations on real tori. We show convergence in law of the associated point processes and explain connections to complex Monge–Ampère equations on abelian varieties and optimal transport.

The Matsubara-Fradkin Thermodynamical Quantization of Podolsky Electrodynamics

, 2011
In this work we apply the Matsubara-Fradkin formalism and the Nakanishi's auxiliary field method to the quantization of the Podolsky electrodynamics in thermodynamic equilibrium.

Real-world study of efgartigimod in AChR antibody-positive generalized myasthenia gravis: thymus status, multi-domain symptom improvement and steroid-sparing effect

Frontiers in Immunology
BackgroundEfgartigimod has been approved for the treatment of gMG. However, real-world evidence regarding its efficacy across various functional domains in patients with differing thymic statuses, as well as its steroid-sparing effect when used in ...

Counting Real Zeros of Analytic Functions Satisfying Linear Ordinary Differential Equations

Journal of Differential Equations, 1996
Let \(K\) be a compact real segment and let \(U\) be a simply-connected open subset of the complex plane containing \(K\). Suppose that \(f\) satisfies a linear differential equation of the form \(a_0 f^{(\nu)}+ a_1 f^{(\nu- 1)}+ \cdots+ a_{\nu- 1} f'+ a_\nu f=0\) where \(f\) and the coefficients \(a_k\) are analytic in \(U\) and continuous in the ...

Recovering Holomorphic Functions from Their Real or Imaginary Parts without the Cauchy--Riemann Equations [PDF]

SIAM Review, 2004
Summary: Students of elementary complex analysis usually begin by seeing the derivation of the Cauchy--Riemann equations. A topic of interest to both the development of the theory and its applications is the reconstruction of a holomorphic function from its real part, or the extraction of the imaginary part from the real part, or vice versa.

A survey on fractional variational calculus

, 2018
Main results and techniques of the fractional calculus of variations are surveyed. We consider variational problems containing Caputo derivatives and study them using both indirect and direct methods.
