The primitive element theorem of field theory answers the question of which finite field extensions have primitive elements. It is not, for example, immediately obvious that if one adjoins to the field Q of rational numbers roots of both polynomials. X 2 − 2 and X 2 − 3, say α and β respectively, to get a field K = Q(α, β) of degree 4 over Q, that K is Q(γ) for a primitive element γ. The primitive elements provide sufficient information about the foundry process to design, lay out, and tape out. These elements, shown in Fig. 4.29, are the design guide, technology file (tech file), and DRC deck. The design guide can include mask layer names, types (negative or positive), opacities, thicknesses, purposes, stress gradients .... In field theory, the primitive element theorem is a result characterizing the finite degree field extensions that can be generated by a single element. Such a generating element is called a primitive element of the field extension, and the extension is called a simple extension in this case. The theorem states that a finite extension is simple if and only if there are only finitely.

A primitive element of a Hopf algebra is an element ... element of a finite field that generates its multiplicative group. Finnish: primitiivinen alkio; element of a lattice that is not a positive multiple of another element. Finnish: primitiivinen alkio;. For GF (256) = GF (2 8 ), the prime factors of 256-1 = 255 are: 3, 5, 17. The combinations to test for are 3 x 5 = 15, 3 x 17 = 51, 5 x 17 = 85. There's no need to test for 3 x 5 x 17 = 255, since any element raised to the 255 power = 1. Let α = a potential candidate for a primitive element, then only the first 3 of the 4 cases below have to. Arithmetic of finite fields is not only important for other branches of mathematics but also widely used in applications such as coding and cryptography. A primitive element of a finite field is of particular interest since it enables one to represent all other elements of the field.. . The primitive element is β = x + 1. To show that β 15 = 1, we carry out a binomial expansion and a polynomial division and conclude that (x + 1) 15 = 1 mod (x 4 + x 3 + x 2 + x + 1). Now β 2 = (x + 1) · (x + 1) = x 2 + 1. Then β k+1 = βk(x + 1). Conversely, every nonzero element in a finite field is a root of unity in that field. See Root of unity modulo n and Finite field for further details.

Example: Let ω be a primitive element of GF(4). The elements of GF(4) are then 0, ω, ω2, ω3. Multiplication is easily done in this representation (just add exponents mod 3), but addition is not obvious. IMMUNOHISTOCHEMISTRY AS A LABORATORY TEST Although they do not publicize it, pathologists have long recognized their fallibility. 1 As a result, more objective means of validating morphologic judgments have been sought. Stains using histochemical methods are of value in accentuating morphologic features but do not provide objective evidence of the. In this case, a primitive element is also called a primitive root modulo q. For example, 2 is a primitive element of the field GF(3) and GF(5), but not of GF(7) since it generates the cyclic subgroup {2, 4, 1} of order 3; however, 3 is a primitive element of GF(7).
