Quantum mechanics is formulated entirely in the language of linear functional analysis. Quantum Mechanics

Functional analysis transforms the question "Does this PDE have a solution?" into "Does an operator equation have a solution in a specific function space?" Using (spaces of functions with weak derivatives), mathematicians use the Lax-Milgram theorem (linear) or Minty-Browder theory (nonlinear) to prove the existence and uniqueness of solutions to heat, wave, and fluid equations.
