Diagonal intersection is a term used in mathematics, especially in set theory. If is an ordinal number and is a sequence of subsets of , then the diagonal intersection, denoted by is defined to be That is, an ordinal is in the diagonal intersection if and only if it is contained in the first members of the sequence. This is the same as where the closed interval from 0 to is used toavoid restricting the range of the intersection. (Wikipedia).
What are the Angle Relationships for Parallel Lines and a Transversal
๐ Learn about converse theorems of parallel lines and a transversal. Two lines are said to be parallel when they have the same slope and are drawn straight to each other such that they cannot meet. In geometry, parallel lines are identified by two arrow heads or two small lines indicated i

Pierrick Bousseau - Gromov-Witten Invariants of Complete Intersections III
I will describe an inductive algorithm computing Gromov-Witten invariants in all genera with arbitrary insertions of all smooth complete intersections in projective space. This uses a monodromy analysis, as well as new degeneration and splitting formulas for nodal Gromov--Witten invariants
