In: The Fourth Conference of Mathematical Society of the Republic of Moldova dedicated to the centenary of V. Andrunachievici (1917-1997): Proceeding CMSM4, June28-July2, 2017. Ch.: CEP USM, 2017, pp. 117-120. ISBN 978-9975-71-915-5.78-9975-71-915-5https://msuir.usm.md/handle/123456789/1656We prove that the recursive derivatives of order 1 of isotopic left Bol loops are isotopic and that every loop, isotopic to a recursively 1-differentiable left Bol loop, is recursively 1-differentiable.The recursive differentiability of di-associative loops is also considered.enRecursively differentiable quasigrouprecursive derivativeisostrophecoreLIP-loopleft Bol loopArticle
