摘要
The Lie-Trotter-Kato product formula has been recently extended into Hadamard spaces by Stojkovic [Approximation for convex functionals on non-positively curved spaces and the Trotter-Kato product formula, Adv. Calc. Var. 5 (2012) 77-216]. The aim of our short note is to give a simpler proof relying upon weak convergence instead of an ultrapower technique.
