Complexity of deciding whether a tropical linear prevariety is a tropical variety [PDF]
arXiv, 2018 We give an algorithm, with a singly exponential complexity, deciding whether a tropical linear prevariety is a tropical linear variety. The algorithm relies on a criterion to be a tropical linear variety in terms of a duality between the tropical orthogonalization $A^\perp$ and the double tropical orthogonalization $A^{\perp \perp}$ of a subset $A$ of ...

Medicina tropical : enfermedad del sueño
, 2014 [ES]Raquel Cade (Angie Dickinson), una misionera, viaja al Congo Belga en 1939 para ayudar como enfermera al Dr. Bikel (Douglas Spencer) en el Hospital de la Misión de Dibela. Nada más llegar, el médico fallece de un ataque cardiaco y Raquel tiene que enfrentarse con las costumbres y creencias religiosas de los nativos.

Representing tropical linear spaces by circuits [PDF]
arXiv, 2006 We study representations of tropical linear spaces as intersections of tropical hyperplanes of circuits. For several classes of matroids, we describe minimal tropical bases. We also show that every realizable tropical linear space has a natural, tropically linear parametrization involving its cocircuits.

Medicina tropical: ¿Realidad científica o estratégia goepolítica?
Ide@sostenible: espacio de reflexión y comunicación en desarrollo sostenible, 2004 Trópico, naturaleza tropical, enfermedades tropicales y medicina tropical, significados sin significantes, son conceptos influenciados, en el decurso de los aconteceres, por posturas, ideologías e intereses —sociales, económicos, geopolíticos, militares, religiosos, académicos, tecnológicos y científicos, a veces contradictorios—, por tanto con ...

Complex tropical localization, coamoebas, and mirror tropical hypersurfaces [PDF]
arXiv, 2008 We introduce in this paper the concept of tropical mirror hypersurfaces and we prove a complex tropical localization Theorem which is a version of Kapranov's Theorem \cite{K-00} in tropical geometry. We give a geometric and a topological equivalence between coamoebas of complex algebraic hypersurfaces defined by a maximally sparse polynomial and ...

Tropical Quadrics Through Three Points [PDF]
arXiv, 2010 We tropicalize the rational map that takes triples of points in the projective plane to the plane of quadrics passing through these points. The image of its tropicalization is contained in the tropicalization of its image. We identify these objects inside the tropical Grassmannian of planes in projective 5-space, and we explore a small tropical Hilbert

El concepto nosográfico de la Medicina Tropical
Anales de la Facultad de Medicina, 2014 La creación de la cátedra de enfermedades tropicales, que tengo el honor de regentar interinamente, ha venido a satisfacer la necesidad imperiosa que había, de ampliar, en la extensión posible el estudio de esas morbosis, que tan de cerca nos interesan, aliviando a la vez, la pesada labor de la asignatura de nosografía médica, cuyas divisiones ...

Tropical Computations in polymake [PDF]
Algorithmic and experimental methods in algebra, geometry, and
number theory, 361-385, Springer, Cham, 2017, 2016 We give an overview of recently implemented polymake features for computations in tropical geometry. The main focus is on explicit examples rather than technical explanations. Our computations employ tropical hypersurfaces, moduli of tropical plane curves, tropical linear spaces and Grassmannians, lines on tropical cubic surfaces as well as ...
