    Bulk Viscous LRS Biachi-I Universe with variable GG and decaying Λ\Lambda

    Full text link
    The present study deals with spatially homogeneous and totally anisotropic locally rotationally symmetric (LRS) Bianchi type I cosmological model with variable GG and Λ\Lambda in presence of imperfect fluid. To get the deterministic model of Universe, we assume that the expansion (θ)(\theta) in the model is proportional to shear (σ)(\sigma). This condition leads to A=BnA=\ell B^{n}, where AA,\;BB are metric potential. The cosmological constant Λ\Lambda is found to be decreasing function of time and it approaches a small positive value at late time which is supported by recent Supernovae Ia (SN Ia) observations. Also it is evident that the distance modulus curve of derived model matches with observations perfectly.Comment: 11 pages, 4 figures and 1 table, Accepted for publication in Astrophysics and Space Scienc

    La intervención estatal en la economía: elementos de análisis para el caso colombiano

    Get PDF
    Un análisis histórico muestra el surgimiento, desaparición, permanencia e influencia de escuelas de pensamiento económico que conceptúan de modo diverso el rol que debe desempeñar el Estado con respecto a la economía; a su vez, la relación Estado-Economía está mediada por la perspectiva antropológica que se tenga. Colombia ha sido receptaria, y en pocos casos creadora, de varias de las propuestas metodológicas de estas escuelas que han influido en la legislación y en la conformación de la economía de nuestro país.AbstractA historical analysis shows the appearance, disappearance, permanency and influence of the schools of economic theories that conceptualize in diverse ways the role that the State must perform with respect to the economy; at the same time, the State-Economy relationship is measured by the anthropologic perspective present at the moment. Colombia has been a receptionist and in few cases creator, of various methodological proposals of these schools that had influenced the legislation and the creation of the economy in our country
