  • Hyperfinite type II factor, a unique von Neumann algebra that is a factor of type II and also hyperfinite
• Hyper-finite field, an uncountable field similar in many ways to finite fields
• Uniformly hyperfinite algebra, a C*-algebra that can be written as the closure of an increasing union of finite-dimensional full matrix algebras
