A Dedekind group is a specific type of group in the field of abstract algebra, characterized by certain structural properties. The most common definition is that a Dedekind group is a group in which every subgroup is normal. This means that for any subgroup \( H \) of a Dedekind group \( G \), the condition \( gHg^{-1} = H \) holds for every element \( g \) in \( G \).

De Sitter invariant special relativity refers to a theoretical framework that extends the principles of special relativity to include de Sitter space, which is a model of spacetime that includes a positive cosmological constant. This framework can be seen as an extension of the usual flat Minkowski spacetime of special relativity, incorporating the geometric properties associated with de Sitter space, which has a constant positive curvature.

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.
