We revise the strong convergent Chernoff product formula and extend it, in a Hilbert space, to convergence in the operator-norm topology. Main results deal with the self-adjoint Chernoff product formula. The nonself-adjoint case concerns the quasi-sectorial contractions.

Chernoff 乘积公式的注意事项

我们修改了强收敛 Chernoff 乘积公式，并将其在 Hilbert 空间中扩展到算子范数拓扑中的收敛。主要结果处理自伴随 Chernoff 乘积公式。非自伴随案例涉及准部门收缩。
