Dan Rogalski: Artin-Schelter regular algebras is a survey on AS-regular algebras, the algebras responsible in noncommutative algebraic geometry for noncommutative projective space. A must-read for anyone new to the field.

Hiroshi Iritani: Quantum cohomology of blowups and Hiroshi Iritani, Yuki Koto: Quantum cohomology of projective bundles show that the quantum cohomology of a blowup resp. projective bundle behave as one would expect, under the mirror symmetry correspondence and the fact that we know Orlov's blowup formula and projective bundle formula. Really cool!

Hodge numbers for smooth Calabi–Yau 3-folds and Topological invariants for known smooth Calabi–Yau 3-folds of Picard number one are two visualisations of numerical data appearing in the classification of Calabi-Yau 3-folds. Really really cool!
