Where H is a mathematical operator called Hamiltonian.

Where H is a mathematical operator ,called Hamiltonian operator.

The NTCF model (12) is a linear or non-linear, multi-variable operator equation (or set of equations).

In basic linear algebra, the dual of a vector space V is the space of linear functionals on V, i.

This leads to the result that the expectation operator is linear.

Associated with each system property A is a linear, Hermitian operator .

In normed spaces a linear operator is continuous if and only if it is bounded.

This property says that the Laplace transform is a linear operation.

This is possible because the function y(x){\displaystyle y(x)} is being acted on by a linear operator.

Here G is a non-linear operator and cannot be separated to represent a linear mapping of the model parameters that form m into the data.

(The definition of a homomorphism depends on the type of algebraic structure; see, for example, group homomorphism, ring homomorphism, and linear operator).
