| 1. | The conformal symmetry is associated with the vanishing of the beta function.
|
| 2. | Here \ mathrm { B } is the beta function.
|
| 3. | Which is a beta function, known as Veneziano amplitude.
|
| 4. | So it is necessary to require that beta functions at two loops are
|
| 5. | Euler defined the beta function and the gamma function.
|
| 6. | :The beta function article says Jacques Binet gave the function its name.
|
| 7. | If a beta function is positive, the corresponding coupling increases with increasing energy.
|
| 8. | For 1 } }, the incomplete beta function coincides with the complete beta function.
|
| 9. | For 1 } }, the incomplete beta function coincides with the complete beta function.
|
| 10. | It was this beta function which was apparently found before full string theory was developed.
