Your Introduction to Group Theory for physicists is really good.
Did you do any other Group Theory notes ?
Recently, i have a primesense 3d camera and i m beginner in openNi, Nite and c++.
i have a project for calculating the volume of a box with this camera.
i wondered if you can share ur knowledge as i saw ur interesting paper.

Dear Prof. Steinkirch,
This is Bardia Najjari, an undergrad physics student with the university of Tehran Iran,
I was searching the net looking for some definitions for my Group Theory course when I came across your book. and I wanted to thank you for kindly uploading your book and making it accessible for free. Actually it was pretty useful for me. I just wanted to say thanks.

I have found QFT and Group Theory notes on your site. They are very
useful. I cordially thank you for writing these up! Now a days I am
struggling with Srednicki's QFT and have found this book terse. I am
self-studying it and it is my first QFT book. In this case, your notes
are such a relief! Alhamdulillah! If you have any other notes on QFT
compatible with Srednicki's $\phi^3$ theory, please let me know.

Dear Dr Marina von Steinkirch,
I have been reading your interesting notes on :" Introduction group theory for physicists",
Could please give much more information, or a reference, on the spinor classification table of page 65.
I have a problem to link this classifcation with the one concerning euclidian Majorana spinors given in the work by C. Wetterich entiteled: Spinors in euclidian field theory, ArXiv 1002.3556.
Thank you in advance.
With my best regards

I am a mathematician (group theorist) working in Kac-Moody theory.
I realized that physicists constructed finite-dimensional representations of the "maximal compact" subgroups/subalgebras of the E(10) Kac-Moody group/algebra.
It turns out that this representation is a generalization of the 1/2 spin representation of Spin(10)/so(10) and that, in fact, these representations can be generalized to arbitrary diagrams. (See attached manuscript.)
Physicists also constructed higher finite-dimensional spin representations of these objects, see
Unfortunately, I totally fail understanding the symbols physicists use in that context. In fact, I do not even know how to write down the 3/2 spin representation for Spin(5)=Sp(4). I just know that I am looking for 32 by 32 matrices.
While google-ing, I came across your very nice lecture notes on group theory. Do you maybe know where to find/how to construct concrete 32 by 32 matrices for this 3/2 spin representation?

Hello, my name is Angel. I just started learning matlab and I'm interested in the face morphing. I saw your code to learn something and would like some information: in function morph, when you add the corner points
% Add points on the corners of the images
[h, w] = size (image1);
image1_points = [image1_points, 1.1, 1, h, w, 1, w, h];
[h, w, number_ch] = size (image2);
image2_points = [image2_points, 1.1, 1, h, w, 1, w, h];
What is "number_ch"?
I really hope you can help me. In any case, I thank you also for your support.
See you soon.
