An enveloping von Neumann algebra is a concept from the field of functional analysis, specifically in the context of operator algebras. To understand this concept, we first need to clarify what a von Neumann algebra is. A **von Neumann algebra** is a *-subalgebra of bounded operators on a Hilbert space that is closed in the weak operator topology and contains the identity operator.
The Fifth-order Korteweg–De Vries (KdV) equation is a mathematical model that extends the classical KdV equation, which is used to describe shallow water waves and other dispersive wave phenomena.
Friedrichs's inequality is a fundamental result in the field of functional analysis and partial differential equations. It provides a way to control the norm of a function in a Sobolev space by the norm of its gradient. Specifically, it is often used in the context of Sobolev spaces \( W^{1,p} \) and \( L^p \) spaces.
The Mandelbox is a type of fractal, specifically a 3D fractal that is an extension of the Mandelbrot set. It was discovered by artist and mathematician Bert Wang. The Mandelbox fractal is generated using a combination of simple transformations and complex mathematical rules, primarily involving iterations of mathematical functions. The structure of the Mandelbox is notable for its intricate, self-similar shapes and the depth of detail that can be found within it, which can be zoomed into indefinitely.
Jean Favard is a French mathematician known for his work in the field of analysis, particularly for his contributions to the theory of functions of several variables, including the Favard theorem related to set functions and measures.

The Pansu derivative is a concept from the field of geometric measure theory and analysis on metric spaces, particularly related to the study of Lipschitz maps and differentiability in the context of differentiable structures on metric spaces. It is named after Pierre Pansu, who introduced the idea while investigating the behavior of Lipschitz functions on certain types of spaces, especially in relation to their geometry.
The Sarason interpolation theorem is a result in complex analysis related to the theory of functional spaces, particularly in the context of the Hardy space \( H^2 \). It provides a criterion for the existence of an analytic function that interpolates a given sequence of points in the unit disk, subject to certain conditions.
The Szász–Mirakjan–Kantorovich operator is a mathematical operator used in approximation theory, particularly in the context of approximating functions using linear positive operators. This operator is a generalization of the Szász operator, which itself is a well-known tool for function approximation.

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
