Ind-objects in C form a category ind-C.. Two ind-objects : and : determine a functor I op x J Sets,. namely the functor ((), ()). The set of morphisms between F and G in Ind(C) is defined to be the colimit of this functor in the second variable, followed by the limit in the first variable:
In solid-state physics, the valence band and conduction band are the bands closest to the Fermi level, and thus determine the electrical conductivity of the solid. In nonmetals, the valence band is the highest range of electron energies in which electrons are normally present at absolute zero temperature, while the conduction band is the lowest range of vacant electronic states.
The term complete partial order, abbreviated cpo, has several possible meanings depending on context. A partially ordered set is a directed-complete partial order (dcpo) if each of its directed subsets has a supremum. (A subset of a partial order is directed if it is non-empty and every pair of elements has an upper bound in the subset.)
Heads up to anyone who is a freelancer, independent contractor, business owner, property renter or just a hobbyist who occasionally sells their creations: If you accept business-related income ...
The U.S. Commerce Department on Thursday finalized an award to SK Hynix of up to $458 million in government grants to help fund an advanced chip packaging plant and research and development ...
Conversely, elements with a partially filled d shell will increase the magnetic moment by an amount proportional to number of missing electrons. Investigated by the physicists John C. Slater [ 2 ] and Linus Pauling [ 3 ] in the 1930s, the rule is a useful approximation for the magnetic properties of many transition metals .
New Orleans Pelicans star Zion Williamson has suffered yet another major setback. The Pelicans announced Saturday the 24-year-old forward has been diagnosed with a left hamstring strain and will ...
