On the classification of polarized surfaces with weakly Ulrich or initialized aCM tangent bundles

Debojyoti Bhattacharya, Ozhan Genc, Angelo Felice Lopez

Counterexamples to the Eisenbud-Schreyer conjecture on the existence of Ulrich bundles have appeared recently (see Anghel [A1] and the third author [Lo]). As weakly Ulrich bundles…

Ulrich bundles on smooth toric threefolds with Picard number $2$

Debojyoti Bhattacharya, Francesco Malaspina

In this paper, we study Ulrich bundles on smooth toric threefolds with Picard number $2$ , namely $P (O_{P^{2}} (a_{0}) \oplus O_{P^{2}} (a_{1}))$ …
