k-ended O(m)×O(n) invariant solutions to the Allen-Cahn equation with infinite Morse index
No full textIn this work we study existence, asymptotic behaviour and stability properties of O(m) x O(n)-invariant solutions of the Allen-Cahn equation Delta u + u(1 - u(2)) = 0 in R-m x R-n with m, n >= 2 and m + n >= 8. We exhibit four families of solutions whose nodal sets are smooth logarithmic corrections of the Lawson cone and with infinite Morse index. This work complements the study started in [23] by Pacard and Wei and [1] by Agudelo, Kowalczyk and Rizzi
The everyday perspective: an approach to socio-spatial segregation in the Comuna 13 neighborhoods of the city of Medellin Since it's intervention and visibility (2004-2019)
No full textilustraciones, diagramas, mapasLa comprensión de los procesos socioespaciales de los territorios requiere más que un acercamiento técnico – espacial, así como una escala de análisis más cercana a lo cotidiano, que es donde se vive lo que sucede en los barrios. Por lo tanto, para comprender la implicación que ha tenido el accionar del Estado en un territorio complejo y fascinante, como lo es la comuna 13 en la ciudad de Medellín, se requirió además de identificar las características del territorio, su historia y su constante transformación, brindar una perspectiva desde lo que se habita como una versión alterna al discurso institucional. Así mismo, con apoyo de revisión cartográfica, recorridos en campo y la consolidación de relatos y datos brindados por los habitantes, se identificará cómo evolucionan procesos implícitos del territorio, como la Segregación socioespacial, cuando se implanta el modelo deseado en la ciudad informal. Es así, que se comprendió el impacto que se ha dado a escala de barrio de la profundización y disminución de procesos de segregación socioespacial luego del accionar del Estado y como esto se refleja desde la perspectiva de lo cotidiano. (Texto tomado de la fuente)Understanding the socio-spatial processes of territories requires more than a technical-spatial approach, as well as a scale of analysis closer to daily life, which is where what happens in the neighborhoods is experienced. In order to understand the implications that actions of the State have had in a complex and fascinating territory, such as the Comuna 13 in the city of Medellín, it is necessary to identify the characteristics of the territory, its history, and its constant transformation, as well as to provide a perspective from what is inhabited as an alternate version of the institutional discourse. The evolution of implicit territorial processes, such as socio-spatial segregation when a desired urban model is implemented in the informal city, will be identified with the support of cartographic review, fieldwork and the consolidation of stories and data provided by the inhabitants. Therefore, it was understood how the actions of the State have influenced the growth and reduction of socio-spatial segregation processes, and how this is reflected on the perspective of everyday life.MaestríaMagister en Estudios Urbano - RegionalesUrbanización y ordenamiento del territorioÁrea Curricular de Arquitectura y Urbanism

Doubling construction for O(m)×O(n) invariant solutions to the Allen–Cahn equation
No full textWe construct new families of two-ended O(m) x O(n)-invariant solutions to the Allen-Cahn equation Delta u + u - u(3)=0 in RN+1, with N >= 7, whose zero level sets diverge logarithmically from the Lawson cone at infinity. The construction is based on a careful study of the Jacobi-To da system on a given O(m) x O(n)-invariant manifold, which is asymptotic to the Lawson cone at infinity

So far known from five localities in Meta Department (Fig. 1). Probably widely distributed within this department’s limits and a typical element of open savanna-like formations. New locality records: COLOMBIA: Meta Department: i) Puerto López; ii) Villavicencio–Restrepo; iii) Serranía de La Macarena; iv) San Martín. Ecological notes. All specimens of A. arcadioi from ‘Cafam Llanos’ and ‘Con Esto Tengo’ were hand-captured at night, after detection with UV light when actively moving. In the former locality, most specimens were found in leaf litter or sandy walls of small streams inside gallery forests, whereas few were collected in borders of forests surrounded by extensive grasslands. In the latter locality, some specimens were found on the walls of a stream or the leaf litter close to it, but most were found on the border of a road in an area strongly influenced by human activities. Even though A. arcadioi was easily encountered in both places, it was noticeably less abundant than Tityus bastosi Lourenço, 1984 in ‘Cafam Llanos’ and Tityus nematochirus Mello-Leitão, 1940 in ‘Con Esto Tengo’, species with which it was found in sympatry. However, Ananteris specimens were very scarce in the places where Tityus Koch, 1836 was abundant.Published as part of Botero-Trujillo, Ricardo & Flórez, Eduardo, 2011, A revisionary approach of Colombian Ananteris (Scorpiones, Buthidae): two new species, a new synonymy, and notes on the value of trichobothria and hemispermatophore for the taxonomy of the group, pp. 1-44 in Zootaxa 2904 (1) on pages 4-9, DOI: 10.11646/zootaxa.2904.1.1, http://zenodo.org/record/528477
