However, phrasing Hilbert reciprocity for number fields in a similar way fails because it crucially hinges on wild ramification effects. We resolve this issue, except at p=2. Our idea is to pinch singularities near the ramification locus. This fattens up K-theory and makes the wild ...

WebJul 5, 2024 · Reciprocity agreements historically have restricted your operations in other states to interstate commerce, leaving you with the burden of purchasing a full-fee plate … In terms of the Hilbert symbol, Hilbert's reciprocity law for an algebraic number field states that $${\displaystyle \prod _{v}(a,b)_{v}=1}$$ where the product is over all finite and infinite places. Over the rational numbers this is equivalent to the law of quadratic reciprocity. To see this take a and b to be distinct odd … See more In mathematics, a reciprocity law is a generalization of the law of quadratic reciprocity to arbitrary monic irreducible polynomials $${\displaystyle f(x)}$$ with integer coefficients. Recall that first reciprocity law, … See more The law of cubic reciprocity for Eisenstein integers states that if α and β are primary (primes congruent to 2 mod 3) then See more Suppose that ζ is an lth root of unity for some odd regular prime l. Since l is regular, we can extend the symbol {} to ideals in a unique way such that $${\displaystyle \left\{{\frac {p}{q}}\right\}^{n}=\left\{{\frac {p^{n}}{q}}\right\}}$$ where … See more Hasse introduced a local analogue of the Artin reciprocity law, called the local reciprocity law. One form of it states that for a finite abelian extension of L/K of local fields, the Artin map is an isomorphism from See more In terms of the Legendre symbol, the law of quadratic reciprocity for positive odd primes states $${\displaystyle \left({\frac {p}{q}}\right)\left({\frac {q}{p}}\right)=(-1)^{{\frac {p-1}{2}}{\frac {q-1}{2}}}.}$$ See more In terms of the quartic residue symbol, the law of quartic reciprocity for Gaussian integers states that if π and θ are primary (congruent to 1 mod (1+i) ) Gaussian primes then See more In the language of ideles, the Artin reciprocity law for a finite extension L/K states that the Artin map from the idele class group CK to the abelianization Gal(L/K) of the Galois group vanishes on NL/K(CL), and induces an isomorphism See more grace church oviedo
Artin reciprocity theorem for Hilbert class field
WebMay 6, 2024 · Hilbert asked for the most general form of a reciprocity law in any algebraic number field, that is, the conditions that determine which polynomials can be solved within the number field. Partial solutions by Emil Artin, Teiji Takagi and Helmut Hasse have pushed the field further, although the question has not been answered in full. Web9. Hilbert Reciprocity Law (classical) 27 10.
