Restriction theorems: from orbits and Chevalley to periods and Galois
Bong Lian, Kamryn Spinelli
Using a new approach based on Galois theory, we study subvarieties of complex representations of reductive groups which satisfy restriction properties on their invariant rings and…

Mirror symmetry for singular double cover Calabi--Yau varieties: quantum test
Tsung-Ju Lee, Bong H. Lian, Shing-Tung Yau
We continue our study on the pairs of singular Calabi--Yau varieties arising from double covers over semi-Fano toric manifolds. In this paper, we first investigate singular CY doub…

Non-commutative resolutions and pre-quotients of Calabi-Yau double covers
Tsung-Ju Lee, Bong H. Lian, Mauricio Romo +1
Following an earlier proposal arXiv:2307.02038 to apply the GLSM formalism to understand the so-called non-commutative resolution, this paper takes one important step further to ex…
