겔폰드-슈나이더 정리
(정리) 겔폰드-슈나이더, 1934
\(\alpha \ne 0\),\(\alpha \ne 1\),\(\beta\notin \mathbb{Q}\) 인 복소수 \(\alpha\)와 \(\beta\) 가 대수적수이면, \(\alpha^{\beta} =e^{\beta \log \alpha\) 는 초월수이다.
Comments
- In general, \(\alpha^{\beta} = \exp\{\beta \log \alpha\}\) is multivalued, where "log" stands for the complex logarithm. This accounts for the phrase "any value of" in the theorem's statement.
- An equivalent formulation of the theorem is the following: if\(\alpha\) and \(\gamma\) are nonzero algebraic numbers, and we take any non-zero logarithm of \(\alpha\), then\((\log \gamma)/(\log \alpha)\) is either rational or transcendental.
- If the restriction that \(\beta\) be algebraic is removed, the statement does not remain true in general (choose \(\alpha=3\) and \(\beta=\log 2/\log 3\), which is transcendental, then \(\alpha^{\beta}=2\) is algebraic). A characterization of the values for \(\alpha\) and \(\beta\) which yield a transcendental \(\alpha^{\beta}\) is not known.
