Theoretical models: necessary reflections. [PDF]
ABSTRACT Objective: To present theoretical-methodological reflections on the elaboration, types, and functions of theoretical models as well as their conceptual and analytic frameworks. Methods: This is an essay, whose material collection was carried out in a non-systematic way, by electing studies exclusively based on the line of argument and ...

Monotone Simultaneous Paths Embeddings in $\mathbb{R}^d$ [PDF]
We study the following problem: Given $k$ paths that share the same vertex set, is there a simultaneous geometric embedding of these paths such that each individual drawing is monotone in some direction?

Theoretical solar models [PDF]
In the last two decades the large amount of accurate helioseismic data has open a new possibility to sound the stellar interiors and to test the stellar evolution theory. This has particularly impulsed a critical reexamination of the basic assumptions and physical inputs in solar modelling.
