芝诺产品公式重新审视
Zeno product formula revisited
摘要:
我们引入了一个新的乘积公式,它结合了一个正交投影与一个非负算子的复变函数。在复变函数的某些假设下,证明了乘积公式的强收敛性.在更严格的假设下,甚至算子范数收敛性也得到了验证。当通常的非衰变观测量被Davies意义下的广义观测量所代替时,该公式可用于描述Zeno动力学。
英文摘要:
We introduce a new product formula which combines an orthogonal projection with a complex function of a non-negative operator. Under certain assumptions on the complex function the strong convergence of the product formula is shown. Under more restrictive assumptions even operator-norm convergence is verified. The mentioned formula can be used to describe Zeno dynamics in the situation when the usual non-decay measurement is replaced by a particular generalized observables in the sense of Davies.
