Eigenfunction expansions associated with pairs of ordinary differential expressions
Let L and M be two formally symmetric \(m\times m\) systems of ordinary differential expressions of orders n and \(\nu\) respectively, defined on an open interval \(\iota\) \(\subset {\mathbb{R}}\) with coefficients which are sufficiently often differentiable and such that the leading coefficient of M is invertible on \(\iota\) and that, at least in ...

"Ordinary Life"; as a Polyphonic Composition [PDF]
Čapek’s novel “Ordinary Life” is interpreted from the point of a narrative approach. The authors argue that Čapek’s novel, published in 1934, anticipates more recent narrative approaches in psychology, in which identity is conceived as a permanent ...

Explicit expressions for meromorphic solutions of autonomous nonlinear ordinary differential equations [PDF]
Meromorphic solutions of autonomous nonlinear ordinary differential equations are studied. An algorithm for constructing meromorphic solutions in explicit form is presented. General expressions for meromorphic solutions (including rational, periodic, elliptic) are found for a wide class of autonomous nonlinear ordinary differential equations.

World-Line Path Integral for the Propagator Expressed as an Ordinary Integral: Concept and Applications [PDF]
The (Feynman) propagator $G(x_2,x_1)$ encodes the entire dynamics of a massive, free scalar field propagating in an arbitrary curved spacetime. The usual procedures for computing the propagator -- either as a time ordered correlator or from a partition function defined through a path integral -- requires introduction of a field $ϕ(x)$ and its action ...

In the mathematical modeling of biochemical reactions, a convenient standard approach is to use ordinary differential equations (ODEs) that follow the law of mass action.

Generation and Identification of Ordinary Differential Equations of Maximal Symmetry Algebra
An effective method for generating linear ordinary differential equations of maximal symmetry in their most general form is found, and an explicit expression for the point transformation reducing the equation to its canonical form is obtained.

Non-Ordinary Mental Expressions (NOMEs): Clues on the Nature of the Human Mind
The aim of this paper is to describe some ostensibly odd, Non-Ordinary-Mental Expressions (NOMEs), that have been considered implausible, illusory or hallucinatory phenomena, possible symptoms of disorders of the neurological or psychological functioning.
