Linear Operators in Quantum Mechanics
In quantum mechanics, physical observables correspond to Hermitian linear operators defined on a complex Hilbert space, where measurable outcomes are strictly real eigenvalues and system states at definite values are orthonormal eigenvectors. The theory is governed by the postulates that measurement probabilities are derived from the squared magnitude of probability amplitudes (inner products) between state vectors and operator eigenvectors, while non-commuting operators represent incompatible observables with simultaneous indefiniteness.
