A survey on the Le-Murakami-Ohtsuki invariant for closed 3-manifolds
Benjamin Enriquez, Anderson Vera
We review the original approach to the Le-Murakami-Ohtsuki (LMO) invariant of closed 3-manifolds (as opposed to the later approach based on the Aarhus integral). Following the idea…
Double Johnson filtrations for mapping class groups
Kazuo Habiro, Anderson Vera
We first develop a general theory of Johnson filtrations and Johnson homomorphisms for a group acting on another group equipped with a filtration indexed by a "good" ordere…
Alternative versions of the Johnson homomorphisms and the LMO functor
Anderson Vera
Let be a compact connected oriented surface with one boundary component and let denote the mapping class group of . By considering the action of …
Johnson-Levine Homomorphisms and the tree reduction of the LMO functor
Anderson Vera
Let M denote the mapping class group of S, a compact connected oriented surface with one boundary component. The action of M on the nilpotent quotients of the fundamental group of…
Reflexive Numbers and Berger Graphs from Calabi-Yau Spaces
L. N. Lipatov, A. Sabio Vera, V. N. Velizhanin +1
We review the Batyrev approach to Calabi-Yau spaces based on reflexive weight vectors. The Universal CY algebra gives a possibility to construct the corresponding reflexive numbers…
