The Heegaard Floer d-invariant for more rational homology spheres
Isabella Khan
The Heegaard Floer d-invariant for a rational homology sphere Y and spin-structure is defined as the minimal absolute grading of a generator of $HF^+(Y; \mathfra…

Koszul dual -algebras from star-shaped diagrams -- part 2
Isabella Khan
This paper proves a Koszul duality result between weighted -algebras constructed in the author's previous work. In the process, we construct a new box tensor…

Bordered algebras and the wrapped Fukaya category
Isabella Khan
This paper establishes an isomorphism between endomorphism algebras from the wrapped Fukaya category of a type of punctured surface, and the class of A-infinity algebras related to…

Koszul dual algebras for star-shaped diagrams -- Part 1
Isabella Khan
By slicing the Heegaard diagram for a given -manifold in a particular way, it is possible to construct -bimodules, the tensor product of which retrieves th…
