In mathematics, a semifield is an algebraic structure with two binary operations, addition and multiplication, which is similar to a field, but with some...

The semifield of fractions of a commutative semiring in which every nonzero element is (multiplicatively) cancellative is the smallest semifield in which...

and form a semiring, called the probability semiring; this is in fact a semifield. The logarithm then takes multiplication to addition (log multiplication)...

functions, i.e. the set of concave functions on a given domain form a semifield. Near a strict local maximum in the interior of the domain of a function...

A semi-field study or semifield study is a type of scientific investigation which is intermediate between laboratory study and open field research. This...

algebraic structures related to fields such as quasifields, near-fields and semifields. There are also proper classes with field structure, which are sometimes...

from the California Institute of Technology, with a thesis titled Finite Semifields and Projective Planes. In 1963, after receiving his PhD, Knuth joined...

Below, more conditional properties are discussed. Any field is also a semifield, which in turn is a semiring in which also multiplicative inverses exist...

distributivity instead. A quasifield satisfying both distributive laws is called a semifield, in the sense in which the term is used in projective geometry. Although...
