ON CLASSICAL DE SITTER SOLUTIONS AND PARAMETRIC CONTROL

On classical de Sitter solutions and parametric control

Abstract Finding string backgrounds with de Sitter spacetime, where all approximations and corrections are controlled, is an open problem.We revisit the search for de Sitter solutions in the classical regime for specific type IIB supergravity compactifications on group manifolds, an under-explored corner of the landscape that offers an interesting

Use of microhabitat and activity patterns of two lizard species from a seasonal dry forest in northern Colombia

In this work, the microhabitat use and activity patterns of two lizard species with sympatric distribution were evaluated in a dry forest fragment within the department of Sucre, northern Colombia.Data was collected in May, June, September and October of 2017, using the active search method limited by time (7:00 and 19:00 hours).Substrates used, sp
