Difficulty understanding selective scan in Mamba implementation

[itsPronay]

I’m trying to understand the selective scan operation in Mamba, but I’m having difficulty connecting the implementation with the underlying math/intuition.

Could someone please share good resources (papers, blog posts, or explanations) that clearly explain:

• what selective scan is doing mathematically
• how it relates to state space models
• and how it is implemented efficiently in Mamba

Thanks
