Positivity of line bundles on general blow-ups of abelian surfaces
Sanghyeon Lee, Jaesun Shin
Let be a polarized abelian surface, and let be a line bundle on , where $π:{\rm Bl}_{r}(S) \rightarrow S…
Three dimensional m-quasi Einstein manifolds with degenerate Ricci tensor
Jongsu Kim, Jinwoo Shin
In this article we give a classification of three dimensional m-quasi Einstein manifolds with two distinct Ricci-eigen values. Our study provides explicit description of local and…
Identifying the progenitors of present-day early-type galaxies in observational surveys: correcting `progenitor bias' using the Horizon-AGN simulation
G. Martin, S. Kaviraj, J. E. G. Devriendt +3
As endpoints of the hierarchical mass-assembly process, the stellar populations of local early-type galaxies encode the assembly history of galaxies over cosmic time. We use Horizo…
Two-Dimensional Dirac Fermions Protected by Space-Time Inversion Symmetry in Black Phosphorus
Jimin Kim, Seung Su Baik, Sung Won Jung +5
We report the realization of novel symmetry-protected Dirac fermions in a surface-doped two-dimensional (2D) semiconductor, black phosphorus. The widely tunable band gap of black p…
The -values of the Riemann zeta function near the critical line
Junsoo Ha, Yoonbok Lee
We study the value distribution of the Riemann zeta function near the line . We find an asymptotic formula for the number of -values in the rectangle $ 1/2 + h_1 /…
Quantifying non-Gaussianity of quantum-state correlation
Jiyong Park, Jaehak Lee, Se-Wan Ji +1
We consider how to quantify non-Gaussianity for the correlation of a bipartite quantum state by using various measures such as relative entropy and geometric distances. We first sh…
