- Difference between ≈, ≃, and ≅ - Mathematics Stack Exchange
In mathematical notation, what are the usage differences between the various approximately-equal signs "≈", "≃", and "≅"? The Unicode standard lists all of them inside the Mathematical Operators B
- Calculate the cohomology group of $U(n)$ by spectral sequence.
with fibre U(n − 1) U (n − 1) Then, we try to use spectral sequence and Leray's theorem to calculate Although it seems that we should calculate it by induction, I don't know how to continue Moreover, someone could use any other method as long as it work

- Lie Algebra of U(N) and SO(N) - Mathematics Stack Exchange
U(N) and SO(N) are quite important groups in physics I thought I would find this with an easy google search Apparently NOT! What is the Lie algebra and Lie bracket of the two groups?
- The sequence of integers - Mathematics Stack Exchange
Prove that the sequence $\\{1, 11, 111, 1111, \\ldots\\}$ will contain two numbers whose difference is a multiple of $2017$ I have been computing some of the immediate multiples of $2017$ to see how
- Homotopy groups U(N) and SU(N): $\\pi_m(U(N))=\\pi_m(SU(N))$
Am I correct that homotopy groups of U(N) U (N) and SU(N) S U (N) are the same,
