Beta function (disambiguation)

Beta function, also called the Euler beta function or the Euler integral of the first kind, is a special function in mathematics.

Beta function may also refer to:

• Beta function (physics), details the running of the coupling strengths
• Dirichlet beta function, closely related to the Riemann zeta function
• Gödel's β function, used in mathematical logic to encode sequences of natural numbers
• Beta function (accelerator physics), related to the transverse beam size at a given point in a beam transport system
