Assume |f(z)| >= 1/3|e^(z^2)| for all z in C and that f(0) = 1 and that f(z) is entire. Prove that f(z) = e^(z^2) for all z in C.
How do you start for this.

Liouville's theorem (Complex A) is a mathematical theorem that states that any bounded entire function in the complex plane must be constant. In other words, if a function is analytic and bounded in the entire complex plane, it cannot have any poles or essential singularities.
Liouville's theorem (Complex A) was discovered by French mathematician Joseph Liouville in the 19th century. He is also known for his contributions to other areas of mathematics such as number theory and differential equations.
Liouville's theorem (Complex A) is significant because it provides a powerful tool for analyzing complex functions. It allows us to determine if a function is constant or not based on its behavior in the complex plane. This theorem is also used in the proof of the fundamental theorem of algebra.
No, Liouville's theorem (Complex A) only applies to entire functions, meaning functions that are analytic in the entire complex plane. Functions with poles or essential singularities are not analytic in the entire complex plane and therefore, this theorem cannot be applied to them.
Yes, there are several generalizations of Liouville's theorem (Complex A) that apply to different types of functions. Some examples include Liouville's theorem for harmonic functions, Liouville's theorem for meromorphic functions, and the Picard-Lindelöf theorem, which is a generalization of Liouville's theorem for entire functions that are unbounded.
