Featuring the most recent findings in subject matters from around the mathematical spectrum, this quantity contains ends up in natural arithmetic in addition to quite a number new advances and novel purposes to different fields reminiscent of chance, facts, biology, and computing device technology. All contributions characteristic authors who attended the organization for girls in arithmetic examine Symposium in 2015: this convention, the 3rd in a chain of biennial meetings equipped by way of the organization, attracted over 330 contributors and showcased the examine of ladies mathematicians from academia, undefined, and government.

5) such as HFinst ([0, 1] × Σ, LH0 × LH1 ) HFinst (Y ). 1) is independent of the choice of Heegaard splitting, as required in Step 4. 1. 1. The Heegaard splitting Y = H0− ∪Σ H1 is a decomposition of the morphism [Y ] ∈ (∅, ∅) given by [Y ] = [H0− ] ◦ [H1 ]. Mor Borconn 2+1 2. The representation by symplectic data can be viewed as determining parts of a the functor F : Bor conn 2+1 → Symp by associating to the empty set ∅ ∈ ObjBor conn 2+1 trivial symplectic manifold given by a point F (∅) := pt ∈ ObjSymp , to nonempty the given symplectic manifolds F (Σ) := MΣ , and to surfaces Σ ∈ ObjBorconn 2+1 (∅, Σ) the Lagrangian F (Hi ) := LHi ⊂ pt− × MΣ .

Zg+n ) and observe that Lφ ◦ Lψ = Lφ◦ψ when φ, ψ are composable. This yields a smooth map when φ is holomorphic in the chosen complex structures on Σi , but in general this naive construction only yields the correct map outside of the diagonal. 3. To each attaching circle α ⊂ Σ associate Lα ⊂ MΣ− × MΣ given by Lα := (z1 , . . , zg+n ) , (πα (z2 ), . . , πα (zg+n )) z1 ∈ α, z2 , . . , zg+n ∈ Σ α . Note that this naively constructed subset is not even closed, let alone a smooth submanifold.

Outgoing boundary inclusion pre- resp. post-composed with a diffeomorphism φ. – Critical point cancellations (Yα− , Yβ ), Zφ occur for attaching cycles α, β ⊂ Σ with transverse intersection in a single point; these give rise to a pair of cobordisms Yα− ∈ Mor(Σ , Σ), Yβ ∈ Mor(Σ, Σ ) whose composition is a cylindrical cobordism representing a diffeomorphism φ : Σ → Σ . – Critical point switches (Yα , Yβ ), (Yβ , Yα ) and (Yα− , Yβ ), (Yβ , Yα − ) occur for disjoint attaching cycles α, β ⊂ Σ; these give rise to a pair of cobordisms17 ≥ 2 when discussing connected bordisms since the handle attachments in dimension d = 1 are morphisms between generally disconnected 1-manifolds, so that Bor conn 1+1 does not have useful connected Cerf decompositions.
