    Jan 6, 2019 · The so-called primitive function f f, which was the starting point and so came first, the root meaning of primitive (Lat. primus, first), is what we might call an antiderivative or integral of p p. …

  2. Finding a primitive root of a prime number

    Jan 3, 2015 · How would you find a primitive root of a prime number such as 761? How do you pick the primitive roots to test? Randomly? Thanks

  3. What are primitive roots modulo n? - Mathematics Stack Exchange

    I'm trying to understand what primitive roots are for a given mod n mod n. Wolfram's definition is as follows: A primitive root of a prime p p is an integer g g such that g (mod p) g (mod p) has …

  4. logic - To what extent can Primitive Recursion perform wellfounded ...

    Jul 31, 2024 · In fact, primitive recursive functions can perform a huge variety of set-theoretic tasks, which makes primitive wellfounded recursion straightforward... Or at least, it's straightforward to …

  5. Primitive roots in arithmetic progression - Mathematics Stack Exchange

    Apr 29, 2019 · Let a a be a primitive root modulo odd prime. Show that in an arithmetic progression a + kp a + k p, where k = 0, 1, …, p − 1 k = 0, 1,, p 1 there is exactly one number that is NOT a primitive …

  6. Proving existence of primitive root - Mathematics Stack Exchange

    Nov 30, 2014 · I'm trying to go in a kind of unconventional route and prove the existence of a primitive root \mathchoice (mod p) \mathchoice (mod p) (where p p is a prime) using group theory.

  7. Primitive Roots mod a prime number - Mathematics Stack Exchange

    Mar 5, 2018 · Example of searching another primitive root. $3$ is a primitive root modulo $7$ and $\phi (7)=6$. Thus $3^5=5$ modulo $7$ is the only other p.r. because $2,3,4,6$ are not coprime with $6$ …

  8. When are Idempotents elements of a semisimple algebra primitive

    Jun 26, 2024 · 1 Based on the comments, a primitive central idempotent is a central idempotent that cannot be written as a sum of two central orthogonal idempotents. If we define that a primitive …

  9. Primitive roots modulo n - Mathematics Stack Exchange

    Jul 14, 2014 · It can be proven that a primitive root modulo $n$ exists if and only if $$n \in \ { 1,2 , 4, p^k, 2 p^k \}$$ with $p$ odd prime. For each $n$ of this form there are exactly $\phi (n)$ primitive roots.
