Maximum modulus principle

In mathematics, the maximum modulus principle in complex analysis states that if f is a holomorphic function, then the modulus |f | cannot exhibit a strict local maximum that is properly within the domain of f. In other words, either f is locally a constant function, or, for any point z0 inside the domain of f there exist other points arbitrarily close to z0 at which |f | takes larger values. (Wikipedia).

Maximum modulus principle

Maximum modulus principle In this video, I talk about the maximum modulus principle, which says that the maximum of the modulus of a complex function is attained on the boundary. I also show that the same thing is true for the real and imaginary parts, and finally I discuss the strong max

Complex analysis: Maximum modulus principle

This lecture is part of an online undergraduate course on complex analysis. We prove the maximum modulus principle, and use to to prove the fundamental theorem of algebra and to find the symmetries of the unit disk. For the other lectures in the course see https://www.youtube.com/playli

Extreme Value Theorem Using Critical Points

Calculus: The Extreme Value Theorem for a continuous function f(x) on a closed interval [a, b] is given. Relative maximum and minimum values are defined, and a procedure is given for finding maximums and minimums. Examples given are f(x) = x^2 - 4x on the interval [-1, 3], and f(x) =
