分解型複素数
1. Split-complex numberIn abstract algebra, the split-complex numbers (or hyperbolic numbers) are a two-dimensional commutative algebra over the real numbers different from the complex numbers. Every split-complex number has the form x + y j, where x and y are real numbers. The number j is similar to the imaginary unit i, except that j = 1. As an algebra over the reals, the split-complex numbers are the same as the direct sum of algebras R ⊕ R (under the isomorphism sending x + y j to ).
