Jones calculus
Jones calculus is a matrix method in polarization optics, formulated by R. Clark Jones in 1941, representing fully polarized coherent light with vectors and 2 × 2 matrices.
Jones polynomial
The Jones polynomial is a polynomial invariant of knots and links in three-dimensional space, introduced by Vaughan Jones in 1984. It distinguishes all knots of 10 crossings or fewer, though computing it is #P-hard.

Joram Lindenstrauss
Joram Lindenstrauss (1936–2012) was an Israeli mathematician at the Hebrew University of Jerusalem who co-created the Johnson–Lindenstrauss lemma on dimension reduction and, with Lior Tzafriri, solved the complemented subspace problem in Banach space theory.
Jordan algebra
A Jordan algebra is a commutative non-associative algebra satisfying the Jordan identity, introduced by Pascual Jordan in 1933 as an algebraic foundation for quantum mechanics.
Jordan block
A Jordan block is a square matrix with a single number λ on its main diagonal, 1s on the diagonal above, and 0s everywhere else.
Jordan Ellenberg

The Jordan normal form, also called the Jordan canonical form, is a block-diagonal matrix representing a linear operator when a matrix cannot be diagonalized, with eigenvalues on the diagonal and 1s on the superdiagonal.
Jordan–Wigner transformation
The Jordan–Wigner transformation maps fermionic creation and annihilation operators to qubits, one qubit per mode, using Pauli Z strings to encode fermionic signs; introduced in 1928.
