By mapping the calculation of Mazur bounds to the enumeration of walks on fractal structures. we present exact bounds on the late-time behavior of spin autocorrelation functions in models exhibiting pair-flip dynamics and more general $p$-flip dynamics. While the pair-flip model is known to exhibit strong Hilbert space fragmentation. the effect of its nontrivial conservation laws on a... https://jeepworldes.shop/product-category/grilles/
