I am now interested in shifted symplectic structures.

I found Zhang's results about symplectic structures (2011, p.3-4, [arXiv link](http://arxiv.org/abs/1111.6294v1), 
Comm. Anal. Geom. 2017) and Pantev–Toen–Vaquié–Vezzosi's results on shifted symplectic structures (2011, see p.1-2, [arXiv link](http://arxiv.org/abs/1111.3209v4), Publ. IHES 2013).

I thought were completely included in the results of Pantev–Toen–Vaquié–Vezzosi. Is this idea correct?

Any comment welcome! Thank you.
