15 theoremの例文
- The "'15 theorem "'says that a quadratic form with integer matrix is universal if it takes the numbers from 1 to 15 as values.
- By the 15 theorem, to verify this, it is sufficient to check that every positive integer up to 15 is a sum of 4 squares . ( This does not give an alternative proof of Lagrange's theorem, because Lagrange's theorem is used in the proof of the 15 theorem .)
