This video will teach students how to convert from fractions to decimals. In particular, I show students how to set up a long division problem using a fraction. Next, I demonstrate the technique of adding zeroes so that an accurate decimal can be found. Thank you for watching and please s

Anna Carla RUSSO - Morita-equivalences for MV-algebras
We shall make a survey of the most recent results obtained in connection with the programme of investigating notable categorical equivalences for MV-algebras from a topos-theoretic perspective commenced in [3]. In [3] and [2] we generalize to a topos-theoretic setting two classical equival

Mr LIMA de CARVALHO e SILVA - From Essential Inclusions to Local Geometric Morphisms
It is well known that, given a site of denition, a subtopos of Grothendieck topos can be obtained by strengthening the Grothendieck topology, thus obtaining an inclusion of toposes. An essential inclusion is one where the inverse image functor of this inclusion has a left adjoint. Kelly an
