Dirichlet Function Math Mathematics Function A natural follow up question one might ask is if there is a function which is continuous on the rational numbers and discontinuous on the irrational numbers. this turns out to be impossible. This modified dirichlet function has many names: thomae, riemann, popcorn, raindrop, ruler. it is defined on the closed interval [0, 1] to be 1 q at reduced rationals p q and 0 elsewhere.

We say that a function g: ℕ → {z ∈ ℂ: | z | = 1} is a modified dirichlet character if g is completely multiplicative, i.e., g (m n) = g (m) g (n), ∀ m, n ∈ ℕ, and agrees with some dirichlet character χ for all but a finite number of primes. Let $ (z n)$ be any sequence such that $ (z n) \rightarrow 0$, i need to show that $h (z n) \rightarrow 0$. but how? it is certainly obvious, but i can't seem to formally provide an argument. first, we show that the above function is not continuous at any real number different from $0$. We can leverage the algebraic limit theorem for functional limits to prove the following theorem, which allows us to build new continuous functions from ones we already know to be continuous.

When viewed from a corner along the line in normal perspective, a quadrant of euclid's orchard turns into the modified dirichlet function (gosper). As we shall see later, thomae's function is not differentiable on the irrationals. in this note, we address whether there is a modification of thomae's function which is differentiable on a subset of the irrationals. in section 2, we prove that thomae's function is not differentiable on the irrationals and define modified versions of thomae's. It is named after carl johannes thomae, but has many other names: the popcorn function, the raindrop function, the countable cloud function, the modified dirichlet function, the ruler function, [2] the riemann function, or the stars over babylon (john horton conway 's name). [3]. A modified dirichlet character f is a completely multiplicative function such that for some dirichlet character χ, f (p) = χ (p) for all but a finite number of primes p ∈ s, and for those exceptional primes p ∈ s, | f (p) | ≤ 1.
