## How is the Riemann zeta function defined?

Riemann zeta function, function useful in number theory for investigating properties of prime numbers. Written as ζ(x), it was originally defined as the infinite series ζ(x) = 1 + 2−x + 3−x + 4−x + ⋯. When x = 1, this series is called the harmonic series, which increases without bound—i.e., its sum is infinite.

**Who proved Riemann zeta function?**

The Riemann hypothesis builds on the prime number theorem, conjectured by Carl Friedrich Gauss in the 1790s and proved in the 1890s by Jacques Hadamard and, independently, by Charles-Jean de La Vallée Poussin.

### What is the zeta function of 1?

The zeta function has a pole, or isolated singularity, at z = 1, where the infinite series diverges to infinity. (A function such as this, which only has isolated singularities, is known as meromorphic.)

**What is zeta function in physics?**

In mathematics and theoretical physics, zeta function regularization is a type of regularization or summability method that assigns finite values to divergent sums or products, and in particular can be used to define determinants and traces of some self-adjoint operators.

## Where is the Riemann zeta function used?

In mathematics, the Riemann zeta function is an important function in number theory. It is related to the distribution of prime numbers. It also has uses in other areas such as physics, probability theory, and applied statistics.

**What is the zeta function machine?**

Alan Turing created this blueprint for a machine designed to calculate trigonometrical functions.

### Is Riemann zeta function solved?

The Riemann hypothesis, a formula related to the distribution of prime numbers, has remained unsolved for more than a century. A famous mathematician today claimed he has solved the Riemann hypothesis, a problem relating to the distribution of prime numbers that has stood unsolved for nearly 160 years.

**Does Zeta mean zero?**

The Riemann zeta function ζ(s) is a function whose argument s may be any complex number other than 1, and whose values are also complex. It has zeros at the negative even integers; that is, ζ(s) = 0 when s is one of −2, −4, −6.. These are called its trivial zeros.
