实结合代数上的对数

Logarithms Over a Real Associative Algebra

Nathan BeDell

摘要:

扩展工作的Freese和库克,其中开发的基本理论的微积分和幂级数的实结合代数,我们研究什么可以说的对数函数的代数。特别地,我们发现对于任何乘法单位零代数的指数函数是单射的,因此代数在指数的图像上有唯一的对数。我们扩展了这个结果,证明了对于一个大类的代数,这些代数的行为与实数和复数上的代数的行为非常相似,这取决于它们是“R型”代数还是“C型”代数。

英文摘要:

Extending the work of Freese and Cook, which develop the basic theory of calculus and power series over real associative algebras, we examine what can be said about the logarithmic functions over an algebra. In particular, we find that for any multiplicative unital nil algebra the exponential function is injective, and hence the algebra has a unique logarithm on the image of the exponential. We extend this result to show that for a large class of algebras, the logarithms behave incredibly similarly to the logarithms over the real and complex numbers depending on if they are "Type-R" or "Type-C" algebras.
