The Arithmetic-Geometric Mean and Periods of Curves of Genus 1 and 2 In more modern number theory, it has been used to compute periods of elliptic curves over C, extended to p-adic fields and even generalised to curves of genus 2. This thesis expands on the generalisation of the AGM to...
For example,let’s use logarithms to find the geometric mean of 10, 100, 1000. Note that the log values are 1, 2, and 3. Therefore, the arithmetic mean of the log values in this set is: \frac{2 \times (1+2+3)}{3}=2
The optimal geometric mean return is an important property of an asset. As a derivative of the underlying asset, the option also has this property. In this paper, we show that the optimal geometric mean returns of a stock and its option are the same from Kelly criterion. It is proved by...
Let pn denote the n-th prime number and let Gn be the geometric mean of the first n primes. It is well-known that Gn/pn → 1/e as n →∞, where e is the Euler's number. The aim of this note is to give various proofs of this fact, equivalent establishments and generalizations....
这就带来了一个问题,当使用算术平均值(Arithmetic Mean)来计算表达时,高表达细胞的数值会对整体表达产生很大影响,从而使结果不够准确。而Geometric Mean可以在考虑到整体表达的同时,能够更好地表示低表达细胞的贡献。 Geometric Mean的计算方法是将每个细胞的表达值取对数,然后将所有细胞的对数值求平均,最后再将结果的...

In this note, we prove the equalities for the weighted geometric mean of two accretive matrices A and B: $$\\begin{aligned} A\\sharp _u B=B\\sharp _{1-u }A=A^{\\frac{1}{2}}(A^{-\\frac{1}{2}}BA^{-\\frac{1}{2}})^{u }A^{\\frac{1}{2}}=B^{\\frac{1}{2}}...
