Some articles on totally real, real:
... will be positive precisely when the field is totally real, and negative if it is a complex cubic field ... Given some real number N > 0 there are only finitely many cubic fields K whose discriminant DK satisfies
... In number theory, a number field K is called totally real if for each embedding of K into the complex numbers the image lies inside the real numbers ... an integer polynomial P, all of the roots of P being real or that the tensor product algebra of K with the real field, over Q, is a product of copies of R ... For example, quadratic fields K of degree 2 over Q are either real (and then totally real), or complex, depending on whether the square root of a positive or ...
Famous quotes containing the words real and/or totally:
“Im not making light of prayers here, but of so-called school prayer, which bears as much resemblance to real spiritual experience as that freeze-dried astronaut food bears to a nice standing rib roast.
