Colby]Fuller Duality between Coalgebras

w x In 8 , K. Morita introduced a useful notion of duality between categories of modules, usually called ‘‘Morita duality.’’ He proved that every duality is given by contravariant hom functors defined by a bimodule which is an injective cogenerator for both categories of modules. On the other hand, the equivalences between categories of comodules over a coalgebra w x were characterized by M. Ta...

Meteorology and Agroforestry Meteorology and Agroforestry

The physical environment affects and interacts with agroforestry systems through tree and crop growth, animal performance, management operations and interactions between the tree/shrub and non-tree components (abbreviated to tree/crop interactions). Interactions take place mainly through the media of microclimate, soil moisture and soil. They may have beneficial or adverse effects, for tree and...

Dynamic Meteorology at the Photosphere of Hd 209458b

We calculate the meteorology of the close-in transiting extrasolar planet HD 209458b using a global, threedimensional atmospheric circulation model. Dynamics are driven by perpetual irradiation of one hemisphere of this tidally locked planet. The simulation predicts global temperature contrasts of ∼500 K at the photosphere and the development of a steady superrotating jet. The jet extends from ...
