  2. Symplectic group - Wikipedia

    en.wikipedia.org/wiki/Symplectic_group

    Sp(n, C) is the complexification of the real group Sp(2n, R). Sp(2n, R) is a real, non-compact, connected, simple Lie group. [4] It has a fundamental group isomorphic to the group of integers under addition. As the real form of a simple Lie group its Lie algebra is a splittable Lie algebra. Some further properties of Sp(2n, R): The exponential ...

  4. C mathematical functions - Wikipedia

    en.wikipedia.org/wiki/C_mathematical_functions

    C mathematical operations are a group of functions in the standard library of the C programming language implementing basic mathematical functions. [1] [2] All functions use floating-point numbers in one manner or another. Different C standards provide different, albeit backwards-compatible, sets of functions.

  5. Names of large numbers - Wikipedia

    en.wikipedia.org/wiki/Names_of_large_numbers

    The naming procedure for large numbers is based on taking the number n occurring in 10 3n+3 (short scale) or 10 6n (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix -illion. In this way, numbers up to 10 3·999+3 = 10 3000 (short scale) or 10 6·999 = 10 5994 (long scale) may be named.

  6. Cantor's diagonal argument - Wikipedia

    Define the bijection g(t) from T to (0, 1): If t is the n th string in sequence s, let g(t) be the n th number in sequence r ; otherwise, g(t) = 0.t 2. To construct a bijection from T to R, start with the tangent function tan(x), which is a bijection from (−π/2, π/2) to R (see the figure shown on the right).

    The C language provides the four ... The total size of u is the size of u.s – which happens to be the sum of the sizes of u.s.u and u.s.d – since s is larger than ...

  8. Polynomial identity ring - Wikipedia

    en.wikipedia.org/wiki/Polynomial_identity_ring

    In particular it satisfies s N for N > n and therefore it is a PI-ring. If R and S are PI-rings then their tensor product over the integers, , is also a PI-ring. If R is a PI-ring, then so is the ring of n × n matrices with coefficients in R.

  9. Schwartz space - Wikipedia

    en.wikipedia.org/wiki/Schwartz_space

    The Fourier transform is a linear isomorphism F:𝒮(R n) → 𝒮(R n). If f ∈ 𝒮(R n) then f is Lipschitz continuous and hence uniformly continuous on R n. 𝒮(R n) is a distinguished locally convex Fréchet Schwartz TVS over the complex numbers. Both 𝒮(R n) and its strong dual space are also: complete Hausdorff locally convex spaces ...
