A Mathematical Model for a Contracting Interstellar Cloud
Meri Lisi, Silvia Totaro (2009)
Bollettino dell'Unione Matematica Italiana
Similarity:
In this paper, we study a one-dimensional mathematical model for a contracting interstellar cloud, with a star inside. Existence and uniqueness of a positive solution are proved by means of the fixed point theorem. A time discretization procedure is given and the case of an expanding interstellar cloud is also considered.

Strong initial segments of models of IΔ₀
Paola D'Aquino, Julia F. Knight (2007)
Fundamenta Mathematicae
Similarity:
McAloon showed that if 𝓐 is a nonstandard model of IΔ₀, then some initial segment of 𝓐 is a nonstandard model of PA. Sommer and D'Aquino characterized, in terms of the Wainer functions, the elements that can belong to such an initial segment. The characterization used work of Ketonen and Solovay, and Paris. Here we give conditions on a model 𝓐 of IΔ₀ guaranteeing that there is an n-elementary initial segment that is a nonstandard model of PA. We also characterize the elements that...
