Classical and modern differential geometry

In summary, "Classical Differential Geometry" is a course that covers the differential geometry of curves and surfaces in three-dimensional Euclidean space, including topics such as mean curvature, Gaussian curvature, and geodesics. The recommended textbook for this course is "Differential Geometry of Curves and Surfaces" by Manfredo do Carmo. For those interested in learning about modern differential geometry while taking this course, some recommended books include "Elements of Differential Geometry" by Millman and Parker, "Differential Geometry: Curves - Surfaces - Manifolds" by Wolfgang Kühnel, and "Differential Forms and Connections" by R. W. R. Darling. It is also suggested to start with a basic understanding of curves and

Im planning on taking a course on classical differential geometry next term. This is the outline:
The differential geometry of curves and surfaces in three-dimensional Euclidean space. Mean curvature and Gaussian curvature. Geodesics. Gauss's Theorema Egregium.
The textbook is "differential geometry of curves and surfaces" by do carmo.

I was wondering if anyone knows a good textbook or set of lecture notes that covers this material and modern differential geometry at the same time. Ideally i will work from this textbook for the class and learn the same ideas in modern differential geometry at the same time. Thanks!

Have you tried a google search?

I found a book by Isham for graduate physics students. It was pub in 1989 from a collection of course notes on coordinate free differential geometry.

There must be more recent publications.

I also found one on DDG for computer work.

What topics of DG are you interested in?

The last chapter covers manifolds.

See my comments on Amazon.

And somewhat more eccentric and with a different emphasis:

I'm mostly interested in how it can be applied to QFT and electromagnetism. I've seen the phrase fibre bundle come up a lot. But I also like DG just for the subject itself. Atleast I liked the section on curves and surfaces that I learned about in my calc course.

Thanks for the reference, the one by Millman and Parker seems to be quite close to what I'm looking for.

The Darling book and Frankel below would be the most relevant to gauge theory.

A couple I forgot:

Frankel, The Geometry of Physics

This has everything you need worked out with pedagogical care, but it's not a quick read.

Schutz, Geometrical Methods of Mathematical Physics

Good on the basics and an easy read, but not much on fiber bundles.

"Differential Geometry of Curves and Surfaces", by Manfredo do Carmo, is great as an introduction to DG because DG should start with the study of curves and surfaces in 3D before going into the geometry of n-dimensional differential manifolds.

If you want to go further then you can use two books

(1) "An Introduction to Manifolds" by Loring Tu. Chapters 1 through 6 make the transition to the differential geometry of manifolds up to Stokes's theorem on manifolds. In my opinion, it's a good idea to read the second book and learn some algebraic topology before reading chapter 7.
https://www.amazon.com/dp/1441973990/?tag=pfamazon01-20

(2) "Riemannian Geometry" by Manfredo do Carmo. This book builds upon the knowledge from the previous book and focuses on the study of distance and curvature on manifolds.
https://www.amazon.com/dp/0817634908/?tag=pfamazon01-20

A good alternative to these two books is "An Introduction to Differentiable Manifolds and Riemannian Geometry" by William Boothby, but it seems that it is more popular with mathematicians than it is with students.

I must add that "at the same time" is not a good idea. DG of curves and surfaces works in R^3. DG of manifolds works on topological spaces that, locally, look like R^n. The mathematical techniques to deal with each situation are significantly different. And I think it's much better to learn DG of curves and surfaces before learning DG on manifolds because the latter can easily get away from our intuition without the former.

Thanks for the book reference. As for learning both at the same time, i wasnt too worried about the techniques and abstraction in modern dg since I have already studied topology. But thanks for the suggestion, ill keep it in mind.

1. What is the difference between classical and modern differential geometry?

Classical differential geometry is rooted in the works of mathematicians such as Euclid and Archimedes, and deals with the study of curves and surfaces in 2D and 3D Euclidean space. Modern differential geometry, on the other hand, is based on the concepts of calculus and vector analysis, and has a more abstract approach to studying geometric objects.

2. How is differential geometry used in other fields of science?

Differential geometry has many applications in physics, particularly in the study of space and time in Einstein's theory of general relativity. It is also used in engineering, computer science, and even biology, to analyze and model complex systems and structures.

3. What are some key concepts in differential geometry?

Some key concepts in differential geometry include the study of curves and surfaces, manifolds, Riemannian geometry, and the use of tensors to describe geometric objects. Other important topics include connections, curvature, and geodesics.

4. Can differential geometry be used to solve real-world problems?

Yes, differential geometry has practical applications in various fields and can be used to solve real-world problems. For example, it can be used to optimize the shape of objects for better aerodynamics or to study the behavior of fluids in fluid mechanics.

5. What kind of skills are needed to study differential geometry?

A strong foundation in mathematics, particularly in calculus, linear algebra, and multivariable analysis, is essential for studying differential geometry. A good understanding of abstract concepts and the ability to think critically and analytically are also important skills for studying this subject.
