The Riemann zeta-function $ \zeta $ is defined by$ \zeta(x) = \displaystyle \sum_{n = 1}^{\infty} \frac {1}{n^x} $and is used in number theory to study the distribution of prime numbers. What is the domain of $ \zeta $ ?

In mathematics, a series is, informally speaking, the sum of the terms of an infinite sequence. The sum of a finite sequence of real numbers is called a finite series. The sum of an infinite sequence of real numbers may or may not have a well-defined sum, and may or may not be equal to the limit of the sequence, if it exists. The study of the sums of infinite sequences is a major area in mathematics known as analysis.

In mathematics, a sequence is an enumerated collection of objects in which repetitions are allowed. Like a set, it contains members (also called elements, or terms). The number of elements (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence. Formally, a sequence can be defined as a function whose domain is either the set of the natural numbers (for infinite sequences) or the set of the first "n" natural numbers (for a finite sequence). A sequence can be thought of as a list of elements with a particular order. Sequences are useful in a number of mathematical disciplines for studying functions, spaces, and other mathematical structures using the convergence properties of sequences. In particular, sequences are the basis for series, which are important in differential equations and analysis. Sequences are also of interest in their own right and can be studied as patterns or puzzles, such as in the study of prime numbers.

so known is that if we replace X with peen, we get a more familiar looking piece. Aires. Now, from this section eleven point three, there's a fact labelled, one that states that this type of Siri's converges if P is bigger than one, diverges otherwise. So in our case, the domain of Zeta, it's pretty hard to draw, So I'll just write in dough. Man is it's the suitable X in the real numbers such that X is larger than one. If you want to write that as Interval, you could write that as one, not including the one because of the strict inequality over here.
