Conductor of dirichlet character
WebA Dirichlet character modulo m m is a group homomorphism from ( Z mZ)∗ ( ℤ m ℤ) * to C∗ ℂ *. Dirichlet characters are usually denoted by the Greek letter χ χ. The function. ( n, m) > 1. is also referred to as a Dirichlet character. The Dirichlet characters modulo m m form a group if one defines χχ′ χ χ ′ to be the function ...

For example, mod 16 $${\displaystyle {\begin{array}{ }&1&3&5&7&9&11&13&… In analytic number theory and related branches of mathematics, a complex-valued arithmetic function $${\displaystyle \chi :\mathbb {Z} \rightarrow \mathbb {C} }$$ is a Dirichlet character of modulus $${\displaystyle m}$$ See more 4) Since $${\displaystyle \gcd(1,m)=1,}$$ property 2) says $${\displaystyle \;\chi (1)\neq 0}$$ so it can be canceled from both sides of $${\displaystyle \chi (1)\chi (1)=\chi (1\times 1)=\chi (1)}$$: $${\displaystyle \chi (1)=1.}$$ 5) Property 3) is … See more The two orthogonality relations are $${\displaystyle \sum _{a{\pmod {m}}}\chi (a)={\begin{cases}\phi (m)&{\text{ if }}\;\chi =\chi _{0}\\0&{\text{ if }}\;\chi \neq \chi _{0}\end{cases}}}$$ and where the first sum has one summand per residue class. See more $${\displaystyle \phi (n)}$$ is Euler's totient function. $${\displaystyle \zeta _{n}}$$ is a complex primitive n-th root of unity: See more The word "character" is used several ways in mathematics. In this section it refers to a homomorphism from a group $${\displaystyle G}$$ (written multiplicatively) to the multiplicative group of the field of complex numbers: See more There are three different cases because the groups $${\displaystyle (\mathbb {Z} /m\mathbb {Z} )^{\times }}$$ have different structures depending on whether $${\displaystyle m}$$ is a power of 2, a power of an odd prime, or the product of prime powers.
