The Schrödinger equation is a central equation in quantum mechanics that describes the time-evolution of a quantum system. The equation is a partial differential equation that relates the wave function of a system to its energy. The wave function, denoted by ψ, is a mathematical representation of the quantum state of a system. "Quantum Mechanics: Theory and Applications" by Ajoy Ghatak
