What is Liouville’s Theorem in Complex Analysis?

Liouville’s theorem in complex analysis states that, “a bounded entire function is a constant function.”

What are Requirements of Liouville’s Theorem?

A function that satisfies Liouville’s Theorem must follow the condition that the function has to be an entire function as well as bounded for all values of z in z-plane.

Can Liouville’s Theorem only be applied to complex numbers?

Yes, Liouville’s Theorem is particularly based on complex analysis and entire functions.

Is Liouville’s Theorem Used for Real-World Applications?

Yes, its applications expand to various fields like physics, engineering, economics etc.

Liouville’s Theorem is named after which Mathematician?

Joseph Liouville a famous French mathematician is the one after which Liouville’s theorem is named.



Liouville’s Theorem

Liouville’s Theorem implies that every entire bounded function must be constant. In other words, according to Liouville’s theorem, “An entire (that is, holomorphic in the whole complex plane C) function cannot be bounded if it is not constant.” This theorem of complex analysis was given by a French mathematician, Joseph Liouville.

In this article, we discuss what Liouville’s theorem is, its application, and its importance in complex analysis.

What is Liouville’s Theorem?

Liouville’s Theorem is a concept of complex analysis that tells us that if a function is bounded, it must be a constant. This theorem focuses on various kinds of functions. It tells us about the distinct properties of certain functions. A mathematician named Joseph Liouville gave this theorem in 1847. But it is also believed that this theorem was already proved in 1844 by another mathematician named Cauchy....
