Abstract
Asaeda, Przytycki and Sikora extended Khovanov homology to links in $I$-bundles over surface. In particular, their construction works for links in the real projective space $\mathbb{RP}^3$. In this thesis, we will present two variations of their construction for null homologous links in $\mathbb{RP}^3$. First, we introduce Khovanov-type homologies which depend on an extra algebraic input $\alpha = (V_0, V_1, f, g)$, consisting of two graded vectors spaces and two maps between them. With some specific choice of $\alpha = \alpha_{\mathit{APS}}$, we recover a reduced version of the Asaeda-Przytycki-Sikora construction. With another choice of $\alpha = \alpha_{\mathit{HF}}$, we construct a spectral sequence from our theory converging to the Heegaard Floer homology of the even branched double cover of $\mathbb{RP}^3$, extending the usual Ozsv\'{a}th-Szab\'{o} spectral sequence for links in $S^3$. Second, we introduce Bar-Natan homology for null homologous links in $\mathbb{RP}^3$ over the field of two elements. It is a deformation of the Asaeda-Przytycki-Sikora construction, in the sense that the associated graded complex with respect to the quantum grading gives their chain complex. We also define an $s$-invariant from this deformation following the same recipe as for links in $S^3$, and establish certain genus bounds based on its properties.
