In functional analysis, a Banach function algebra on a compact Hausdorff space X is unital subalgebra, A, of the commutative C*-algebra C(X) of all continuous, complex-valued functions from X, together with a norm on A that makes it a Banach algebra. A function algebra is said to vanish at a point p if f(p) = 0 for all . A function algebra separates points if for each distinct pair of points , there is a function such that . For every define for . Then is a homomorphism (character) on , non-zero if does not vanish at . Theorem: A Banach function algebra is semisimple (that is its Jacobson radical is equal to zero) and each commutative unital, semisimple Banach algebra is isomorphic (via the Gelfand transform) to a Banach function algebra on its character space (the space of algebra homomorphisms from A into the complex numbers given the relative weak* topology). If the norm on is the uniform norm (or sup-norm) on , then is calleda uniform algebra. Uniform algebras are an important special case of Banach function algebras. (Wikipedia).
In this video, I talk about the definition of a function and properties of functions. I also go over some examples of how to determine whether a relation is a function or not and how to evaluate functions. Enjoy! Facebook: https://www.facebook.com/braingainzofficial Instagram: https://

Algebra 2 2.01a - What is a Function
What is a function? The concept of a function is explained through the use of a specific example of Pressure versus Depth, and the idea of a dependent and an independent variable is discussed. This is the first video in Chapter 2 of the Algebra 2 course by Derek Owens. More info about t

Abstract: I’ll discuss the Banach algebra structure of the spaces of bounded linear operators on ℓp and Lp := Lp(0,1). The main new results are 1. The only non trivial closed ideal in L(Lp), 1 ≤ p [is less than] ∞, that has a left approximate identity is the ideal of compact operators (joi
