A no-go theorem for special Ulrich bundles, with a complement on primary Burniat surfaces

Cristian Anghel, Filip Chindea

Let $X$ be a smooth projective surface with $p_{g} = 0$ , and let $H$ be an ample divisor with $h^{0} (O_{X} (H)) \neq = 0$ , $χ (O_{X} (H)) \geq q$ , and $h^{1} (O_{X} (H)) \neq = 0$ …

AKSZ Descent on Manifolds with Ordinary Corners

Cristian Anghel

Under an explicit formal mapping-space hypothesis, we develop a facewise formulation of the classical AKSZ construction on compact oriented manifolds with ordinary corners. The cod…
