Degenerations of shifted symplectic moduli stacks of sheaves
Let $S$ be a smooth, affine noetherian $\mathbb{C}$-scheme, and let $X/S$ be a smooth, quasi-projective family of Calabi--Yau $d$-folds. We prove that the derived moduli stack of flat families of properly supported coherent sheaves on $X/S$ has a relative $(2-d)$-shifted symplectic structure by generalizing a construct...
