WebIn algebra (in particular in algebraic geometry or algebraic number theory), a valuation is a function on a field that provides a measure of the size or multiplicity of elements of the field. It generalizes to commutative algebra the notion of size inherent in consideration of the degree of a pole or multiplicity of a zero in complex analysis, the degree of divisibility of a … http://virtualmath1.stanford.edu/~conrad/154Page/handouts/normtrace.pdf hi-scan 6046si
