Some memos on Stable Symplectic Structured Space II: Symplectic motives

These memos include the research on ${\mathcal{G}}_{\mathbb{S}}^{alg}$-scheme theory, the definition of symplectic motives over ${\mathcal{G}}_{\mathbb{S}}^{alg}$-schemes and symplectic motivic cohomology. This presents a new research direction.
