On the idempotency of some composite functors

Ramon Flores

In this note we present examples of localization functors (in the category of spaces) whose composition with certain cellularization functors is not idempotent, and vice versa.

Some open questions concerning biological growth

Carlos Escudero

We briefly review the properties of radially growing interfaces and their connection to biological growth. We focus on simplified models which result from the abstraction of only c…

Dynamics of Generalized Hydrodynamics: Hyperbolic and Pseudohyperbolic Burgers Equations

Carlos Escudero

The equations of continuum hydrodynamics can be derived from the Boltzmann equation, which describes rarefied gas dynamics at the kinetic level, by means of the Chapman-Enskog expa…

Regularity theory for the fractional harmonic oscillator

P. R. Stinga, J. L. Torrea

In this paper we develop the theory of Schauder estimates for the fractional harmonic oscillator $H^{σ} = (- Δ + ∣ x ∣^{2})^{σ}$ , $0 < σ < 1$ . More precisely, a new class of smooth functions $C^{k,…

Branching analysis of a countable family of global similarity solutions of a fourth-order thin film equation

P. Alvarez-Caudevilla, V. A. Galaktionov

We show that various asymptotic properties of global solutions of a fourth-order quasilinear thin film equation can be described by branching from corresponding solutions of the li…

Evolutionary game theory: Temporal and spatial effects beyond replicator dynamics

Carlos P. Roca, José A. Cuesta, Angel Sánchez

Evolutionary game dynamics is one of the most fruitful frameworks for studying evolution in different disciplines, from Biology to Economics. Within this context, the approach of c…

Local well posedness for a linear coagulation equation

M. Escobedo, J. J. L. Velazquez

In this paper we derive some a priori estimates for a class of linear coagulation equations with particle fluxes towards large size particles. The derived estimates allow us to pro…

The relation between Pearson's correlation coefficient r and Salton's cosine measure

Leo Egghe, Loet Leydesdorff

The relation between Pearson's correlation coefficient and Salton's cosine measure is revealed based on the different possible values of the division of the L1-norm and the L2-norm…

Fractal Weyl law behavior in an open, chaotic Hamiltonian system

Jordan A. Ramilowski, S. D. Prado, F. Borondo +1

We numerically show fractal Weyl law behavior in an open Hamiltonian system that is described by a smooth potential and which supports numerous above-barrier resonances. This behav…

The canonical 8-form on manifolds with holonomy group Spin(9)

M. Castrillon Lopez, P. M. Gadea, I. Mykytyuk

An explicit expression of the canonical 8-form on a Riemannian manifold with a Spin(9)-structure, in terms of the nine local symmetric involutions involved, is given. The list of e…
