The present paper extends Stetkær’s Algebraic Small Dimension Lemma on semigroups (Stetkær in Aequat Math, 2020) by replacing its involution by an anti-homomorphism that need not be involutive. We apply our result, to give an accessible approach to solve the d’Alembert \( \mu \)-functional equation and the Wilson \(\mu \)-functional equation on compact groups with an anti-homomorphism. This generalizes Yang’s result (Yang in Canad Math Bull 56: 218–224, 2013).

半群上具有反同态的代数小维引理

本文通过用不需要同合的反同态性替换它的对合,在半群上扩展了Stetkær的代数小维引理(Aetat Math,2020年的Stetkær)。我们应用我们的结果,给出了一种可逆的方法来解决带有反同态性的紧群上的d'Alembert \(\ mu \) -函数方程和Wilson \(\ mu \) -函数方程。这可以概括杨的结果(Yang in Canad Math Bull 56:218–224,2013年)。
