	Decomposition of Matrix Groups of Large Degree
		The classical forms are: symplectic (non-degenerate, alternating bilinear), unitary (non-degenerate sesquilinear) or orthogonal (a symmetric bilinear form and a quadratic form).
		The matrix of the form is stored in bilinearForm and the scalars for each generator of G are stored in scalars.
		If the absolutely irreducible group G preserves an orthogonal form modulo scalars, and so as one component a symmetric bilinear form modulo scalars, this function returns the scalars corresponding to the generators of the group of the symmetric bilinear form.

		By analogy with what is done for bilinear forms, equivalence is defined for Hermitian forms (in another terminology, isometry) and, correspondingly, isomorphism (isometry) of Hermitian spaces (in particular, automorphism).
		, a Hermitian form is a symmetric bilinear form, and a skew-Hermitian form is a skew-symmetric or anti-symmetric bilinear form.
		Hermite was the first, in 1853, to consider the forms that bear his name in connection with certain problems of number theory.

		The basis for this consists in the study of special elements in the classical groups and the geometric properties of them, principally the study of transvections, involutions and planar rotations.

		Then for each integer $k\in \lbrack 0,m\rbrack $ the sesquilinear form $\ad^k_AS$ is continuous for the topology induced by $\C{H}$ on $D(A^k)$}.
		However, for the clarity of the exposition, we shall in general distinguish between $\lbrack S,A\rbrack $ (sesquilinear form on $D(A)$) and $\C{A}S$ (bounded operator in $\C{H}$ associated to it), although this is rather pedantic (because of the identification (2.3)).
		Under this condition one has \begin{equation} \label{eq:3.1} \C{A}^k\lbrack S\rbrack \equiv\C{A}^kS=(-1)^k\ad^k_AS=\sum_{i+j=k}\frac{k!}{i!j!} (-1)^iA^iSA^j \end{equation} with the same comment as in the case $k=1$ (i.e.\ $\C{A}^kS$ is the element of $B(\C{H})$ associated to the sesquilinear form on $D(A^k)$ defined by the last member of (3.1)).

		Formally, an inner product space is a vector space V over the field F together with a positive-definite nondegenerate sesquilinear form, called an inner product.
		This theorem can be regarded as an abstract form of Fourier series, in which an arbitrary orthonormal basis plays the role of the sequence of trigonometric polynomials.
		The spectral theorem provides a canonical form for symmetric, unitary and more generally normal operators on finite dimensional inner product spaces.
