- Hadamard parametrix construction, a method of solving second order partial differential equations
- Hadamard's dynamical system, a type of chaotic dynamical system
- Complex analysis and convexity
- Hadamard three-lines theorem, an inequality relating the maximum moduli of a complex analytic function on three parallel lines
- Hadamard three-circle theorem, an inequality relating the maximum moduli of a complex analytic function on three concentric circles
- Hadamard factorization theorem, a method of factorizing an entire function
- Ostrowski–Hadamard gap theorem, a result on the analytic continuation of lacunary power series
