An **automorphic function** is a mathematical function that is related to a specific type of symmetry under a transformation. More formally, in the context of number theory and modular forms, automorphic functions are often defined as functions that are invariant under certain transformations of the domain, commonly associated with groups such as the modular group.
A function \( f: A \rightarrow B \) (where \( A \) and \( B \) are subsets of metric spaces) is said to be **Cauchy-continuous** at a point \( x_0 \in A \) if for every sequence of points \( (x_n) \) in \( A \) that converges to \( x_0 \) (meaning that \( x_n \to x_0 \) as \( n \) approaches infinity
In the context of mathematics, particularly in the field of constructible numbers and constructible functions, a constructible function is typically defined in relation to the concept of constructible numbers in geometry and algebra. ### Constructible Numbers: A number is considered constructible if it can be obtained from the rational numbers using a finite sequence of operations involving addition, subtraction, multiplication, division, and taking square roots.
A proper convex function is a specific type of convex function that has certain properties which make it particularly useful in optimization and analysis.
Singular function by Wikipedia Bot 0
In mathematics, a singular function typically refers to a function that exhibits some form of singularity, which can mean different things depending on the context. Here are a few common interpretations of "singular function": 1. **Singularity in Analysis**: In the context of real analysis, a singular function might refer to a function that is not absolutely continuous.
Megasonic cleaning is a process that uses high-frequency sound waves, typically in the range of 1 to 100 MHz (megahertz), to produce high-energy acoustic waves in a liquid cleaning solution. This technique is particularly effective for cleaning intricate and delicate parts and surfaces, including microelectronics, semiconductor wafers, and precision optical components. The process works by generating cavitation bubbles in the cleaning solution.
Microbubble by Wikipedia Bot 0
Microbubbles are tiny gas-filled bubbles with a diameter typically in the range of 1 to 100 micrometers.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

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!
We have two killer features:
  1. 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-calculus
    Articles 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.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
