The mathematical formulations of quantum mechanics are those mathematical formalisms that permit a rigorous description of quantum mechanics. This mathematical formalism uses mainly a part of functional analysis, especially Hilbert spaces, which are a kind of linear space.

We will explore the fundamental mathematical concepts and properties needed to understand Quantum Mechanics. These concepts will be imperative in understanding the inner working of Quantum Finance.
