Knowing that any such set must have 1-dimensional Lebesgue measure zero and nowhere density, and the fact that there are examples of countable sets both inside and outside of the class BLC, families of Cantor-type sets were focused on. Backed up by numerical experiments (up to degree 128) and analytical results, the conjecture “there exists no perfect set in BLC” was put forward.viii, 42 leaves : charts ; 30 cm.Englishinfo:eu-repo/semantics/openAccessLebesgue constantsCantor type setsFaber basisLagrange interpolationThesisB160498
