Brauer groups of Quot schemes [PDF]
Michigan Mathematical Journal, 2015 Let $X$ be an irreducible smooth complex projective curve. Let ${\mathcal Q}(r,d)$ be the Quot scheme parametrizing all coherent subsheaves of ${\mathcal O}^{\oplus r}_X$ of rank $r$ and degree $-d$. There are natural morphisms ${\mathcal Q}(r,d) \longrightarrow \text{Sym}^d(X)$ and $\text{Sym}^d(X) \longrightarrow \text{Pic}^d(X)$.

Brauer groups of schemes associated to symmetric powers of smooth projective curves in arbitrary characteristics [PDF]
Journal of Pure and Applied Algebra, 2020 In this paper we show that the l^n-torsion part of the cohomological Brauer groups of certain schemes associated to symmetric powers of a projective smooth curve over a separably closed field k are isomorphic, when `l is invertible in k. The schemes considered are the Symmetric powers themselves, then the corresponding Picard schemes and also certain ...

Picard and Brauer Groups of Zariski Schemes [PDF]
Proceedings of the American Mathematical Society, 1986 The Cartier-Yuan exact sequence is used to calculate Picard groups and Brauer groups of Zariski surfaces and their generalizations. A result of Blass-Deligne on the factoriality of general affine Zariski surfaces is extended to all higher dimensional Zariski schemes.

Brauer groups and Galois cohomology for a Krull scheme
Journal of Algebra, 1985 In a previous paper the authors introduced the class group \(Cl(\mathcal C(X))\) and the Brauer group \(Br(\mathcal C(X))\), where \(\mathcal C(X)\) is a suitable category of divisorial lattices over a Krull scheme. In this paper it is shown that there are exact sequences of Galois cohomology which relate the class groups and Brauer groups so defined ...

Brauer group of punctual Quot scheme of points on a smooth projective surface
, 2019 Let $X$ be a smooth projective surface over an algebraically closed field $k$ such that $char(k) \neq 2$. Let $X^{[d]}$ denote the punctual Hilbert scheme of zero dimensional quotients of degree $d$ and $X^{(d)}$ denote the symmetric product of $X$. For $\ell \neq 2$, we give a formula for the $\ell$-primary part of the Brauer group of $X^{[2]}$.

Mackey-functor structure on the Brauer groups of a finite Galois covering of schemes
, 2008 Past studies of the Brauer group of a scheme tells us the importance of the interrelationship among Brauer groups of its finite étale coverings. In this paper, we consider these groups simultaneously, and construct an integrated object "Brauer-Mackey functor".
