DOI: 10.1142/s0218348x21500961
Abstract: We investigate the [Formula: see text]-level Sierpinski carpets including the classical one for [Formula: see text], which are non-p.c.f. self-similar fractals. By using the finitely, many geometric patterns and the self-similar measure, we obtain the… read more here.
