该文利用Banach代数中的函数演算技巧及谱理论知识,定义了从时标到Banach代数中的指数函数,推广了时标上的实值指数函数,并证明该指数函数为有单位元的交换Banach代数中线性时标动态方程的公式解.
In this paper,using functional calculus and spectrum theory of Banach algebra,we give an explicit formula of the general exponential function in Banach algebra on time scales which improves the one in real number.We also prove it to be the unique solution of the IVP of linear dynamical equations in unital commutative Banach algebra on time scales.
