Abstract:
In the attempt to unify constructions in Spectral sequence, Hedden, Baldwin defined the notion of Khovanov-Floer theory. All these spectral sequence share some common feature like, there $E_2$ page is Khovanov Homology. We shall review some algebraic aspect of these spectral sequence and then I shall talk about Khovanov spectrum and how they give rise to the similar kind of Spectral sequences. I shall discuss some structural properties of the Khovanov Spectra. I will end the talk with the question I am working on.
