摘要：

Abstract: Splitting, or decomposition, strategies have been widely used in computations of the numerical solution of differential equations. The methods offer extraordinary features in structure simplicity, computational efficiency and flexibility in multi-physics computations. The basic idea of modern splitting methods, on the other hand, can be traced back to the Baker­-Campbell-­Hausdorff formula which is fundamental in statistic and quantum physics. This talk will provide an insight into similar but different features of modern splitting methods, and discuss their rich connections and applications with different versions of Hausdorff and Trotter formulae in physics.
