SUMMARY

The discussion focuses on the connections between algebraic structures and geometries, emphasizing the need for accessible literature for undergraduates. Participants recommend "Geometries and Groups" by Nikulin and Shafarevich as a suitable resource, highlighting its balance of accessibility and challenge. Additionally, the article from arXiv discusses the relationship between geometric spaces and transformation groups, providing foundational insights. The conversation underscores the importance of understanding the geometric implications of algebraic concepts such as groups, normal subgroups, and the role of complex numbers and quaternions.

PREREQUISITES
  • Understanding of basic algebraic structures, including groups and fields.
  • Familiarity with geometric concepts, particularly Euclidean geometry.
  • Knowledge of complex numbers and their geometric interpretations.
  • Awareness of quaternions and their applications in geometry and rotations.
NEXT STEPS
  • Research "Geometries and Groups" by Nikulin and Shafarevich for foundational knowledge.
  • Explore the article on arXiv regarding transformations and geometric properties.
  • Investigate the geometric implications of normal subgroups and quotient groups.
  • Study the applications of quaternions in geometry and compare them with complex numbers.
USEFUL FOR

Students and educators in mathematics, particularly those interested in the interplay between algebra and geometry, as well as anyone seeking to deepen their understanding of geometric transformations and algebraic structures.

Connections between algebraic structures and geometries are mentioned in almost any course of modern geometry or algebra. There are monographs dedicated to the subject. Unfortunately, the books, I managed to find, are written for professional mathematicians. I am looking for a book that focuses on those connections written with (under)graduate in mind, with thorough explanations and examples (maybe, not just purely mathematical examples, but ones borrowed from physics), that could answer my questions like the following (I know they are incorrectly posed, too vague, even naïve, but this is exactly why I am in need for such a book, to be able to ask right questions):

- why geometries correspond to groups, but not to fields or to rings (those possesses group structure anyway)?
- properties of groups to be abelian or Lie groups; what does it mean for the geometric properties?
- geometric meaning of existence of normal subgroups and quotients; zero dividers?
- complex numbers are intimately related with geometry; what about quaternions, I know they are used to describe rotations, but this seems to be scanty compared to rich geometric applications of complex numbers; why is that so?

Again, I am not looking for answers for the questions above, but for a book that would help me to dissipate darkness surrounding them.

basic fact: given a geometric space, such as a euclidean plane, the set of one to one transformations that preserve the geometric properties like distance, form a group. more interesting, given an abstract group, one can search for a geometric object whose set of transformations are identical with this group.

here is a very well written book, elementary in terms of prerequisites, but still fairly challenging:

Geometries and Groups, by Nikulin and Shafarevich.
 
A recommended book sitting on my desk, that I have not gotten to yet:

I'm grateful to everyone for the suggestions. I'll take a look at all of them.
 
I am studying the mathematical formalism behind non-commutative geometry approach to quantum gravity. I was reading about Hopf algebras and their Drinfeld twist with a specific example of the Moyal-Weyl twist defined as F=exp(-iλ/2θ^(μν)∂_μ⊗∂_ν) where λ is a constant parametar and θ antisymmetric constant tensor. {∂_μ} is the basis of the tangent vector space over the underlying spacetime Now, from my understanding the enveloping algebra which appears in the definition of the Hopf algebra...
