Somos en el mundo... seres, materialidad y paisajes
álvarez Larrain,Alina;
La zaranda de ideas , 2012,
Abstract: this work is a theoretical exercise which has as its objective to reflect on certain concepts related to the archaeology of landscapes and architecture. the importance of practical experience in our activities as beings set in a material world has led us to rethink the question of space and our criteria at the time of its study. we then propose from a dwelling perspective a vision of landscape as a network of relationships between places anchoring the past in the environment, with architecture as an element that shapes this landscape and as an expression of a cultural attitude toward the same landscape. the concepts raised here allow us to think in other terms concerning the architectural evidence from andalhuala, valley of yocavil, and questions the dominant abstract and universal reason perspective (emphasized by the sciences), that deals with the living worlds of different peoples as "world visions" that overlap "true" reality with that of "nature".
El Tratado Antártico, vehículo de paz en un campo minado
Prieto Larrain,M. Cristina;
Universum (Talca) , 2004, DOI: 10.4067/S0718-23762004000100008
Abstract: the history of human activity in antarctic is largely explained by its remoteness and its unique physical characteristics. 99% of its surface, i.e. 14 million km2, is covered by ice with an average depth of 2 km, constituting over 90% of the globe's ice. besides being the coldest continent, it is also the driest, the windiest and the highest, with an average elevation of 2,500 m. the harshness of its environment explains the lack of indigenous human population of the area and the late dates of its recognition. as the legal, political and economic interest in the region took shape, different countries started to assert their right to territorial sovereignty over various parts of the continent. the strong emphasis on sovereignty, particularly in the context of overlapping claims by various nations, resulted in clashes -verbal and physical - which threatened the peaceful relations in antarctic. within this context the antarctic treaty and its supporting agreements and arrangements -collectively, the antarctic treaty system or ats- emerged. the regime was created in 1958-1959 aiming to halt the potentially explosive nature of the sovereignty claims and trying to safeguard the area from any nuclear and military threat. in regards to the claims, those put forward by chile, argentina and the united kingdom, are a good example of overlapping territorial demands based on diverse legal systems. although the ats has been a remarkable agreement, it has also has several problems. in fact, the management of the sovereignty issue has been both its principle problem and its most brilliant achievement. ats has simultaneously frozen a very difficult issue and given time to the evolution of international law, with the hope that the future might bring a non-violent solution in regards to the territorial possession of the continent.

El Tratado Antártico, vehículo de paz en un campo minado
M. Cristina Prieto Larrain
Universum : Revista de Humanidades y Ciencias Sociales , 2004,
Abstract: El 99% de la superficie de la Antártica, esto es 14 millones de Km2, está cubierta por hielos de unos 2 Km de profundidad. Además de ser el continente más frío, la Antártica es también el más seco, ventoso y alto del mundo, con una elevación media de 2.500 Mt. Tales características físicas explican la ausencia de población humana indígena en el área, así como lo tardío de su exploración y explotación por parte de estados europeos y americanos entre otros. Sólo a partir del siglo XVIII comienzan las expediciones al territorio antártico, con finalidades que van desde la investigación científica, pasando por la pesca de ballenas, hasta intentos de anexión territorial por parte de alguna nación. Conforme avanza el siglo XX, continúa la penetración del continente y los reclamos de soberanía sobre distintas áreas de la zona. Esto dio pie a disputas y choques entre estados. Durante la II Guerra Mundial amenazaba con transformarse en un nuevo escenario de enfrentamiento bélico entre las fuerzas enemigas. A lo largo de la Guerra Fría, se ve con temor que la Antártica podría ser tomada como centro de pruebas de armamento convencional y nuclear. A fin de evitar estos males y regularizar la explotación y exploración del continente, nació el Sistema del Tratado Antártico o STA. El régimen fue creado en 1958-1959 y pretendió detener las demandas de soberanía territorial además de salvaguardar el área de cualquier amenaza nuclear y militar. Aunque las partes signatarias tienen un evidente interés de futura anexión territorial, y el STA no ha logrado dar solución al problema de la soberanía sobre el continente, al menos ha congelado una peligrosa fuente de discordia e inestabilidad regional y mundial. Especialmente interesantes son los casos de Chile, Argentina y el Reino Unido, cuyas demandas territoriales sobrepuestas constituyen un buen ejemplo del choque de los títulos de soberanía esgrimidos por diversas naciones, con frecuencia basados en diferentes sistemas jurídicos. Finalmente, el establecimiento del Tratado Antártico ha dado tiempo a la evolución del derecho internacional, con la esperanza de que futuras regulaciones territoriales puedan traer una solución no violenta respecto a la posesión del continente. The history of human activity in Antarctic is largely explained by its remoteness and its unique physical characteristics. 99% of its surface, i.e. 14 million Km2, is covered by ice with an average depth of 2 km, constituting over 90% of the globe's ice.

Arquitectura y paisajes en la localidad arqueológica de Andalhuala (Valle de Yocavil, Catamarca)
Alina álvarez Larrain
Revista del Museo de Antropologia , 2010,
Abstract: The architectural space is set up as part of the cultural landscape is fully involved in the construction and reproduction of domestic and ritual practices and the collective imagination of the community that builds and inhabits it. The Andalhuala archaeological locality is thus presented as an area that allows us to consider what was the construction and use of space on the eastern slope of the valley of Santa Maria or Yocavil whose patterns of settlement were previouly identified from the known to the western flank. We discuss here the evidence recovered from prospecting and surveying architectural in the mentioned locality. The results so far indicate a complex picture of occupations since the beginning of the first millennium D.C. until the final of the late times, comprising a strip space from the lowlands near permanent basins to the lower floors of the Sierra del Aconquija.
K-Theories for Certain Infinite Rank Bundles
Andres Larrain-Hubach
Mathematics , 2011,
Abstract: Several authors have recently constructed characteristic classes for classes of infinite rank vector bundles appearing in topology and physics. These include the tangent bundle to the space of maps between closed manifolds, the infinite rank bundles in the families index theorem, and bundles with pseudodifferential operators as structure group. In this paper, we construct the corresponding K-theories for these types of bundles. We develop the formalism of these theories and use their Chern character to detect a large class of nontrivial elements.
The order of curvature operators on loop groups
Andres Larrain-Hubach
Mathematics , 2009, DOI: 10.1007/s11005-009-0352-1
Abstract: For loop groups (free and based), we compute the exact order of the curvature operator of the Levi-Civita connection depending on a Sobolev space parameter. This extends results of Freed and Maeda-Rosenberg-Torres.
