Extremal Effective Cycles and Nef Line Bundles on $\overline{\rm{M}}_{g,n}$

Daebeom Choi

There has been a growing body of work devoted to the study of effective cones of codimension-$k$ cycles $\text{Eff}^k(\overline{\rm{M}}_{g,n})$ on $\overline{\rm{M}}_{g,n}$,…

Extremal effective curves and non-semiample line bundles on $M_{g, n}$

Daebeom Choi

We develop a new method for establishing the extremality in the closed cone of effective curves on the moduli space of curves and determine the extremality of many boundary $1$ -str…

Conformal Block Divisors for Discrete Series Virasoro VOA $Vir_{2 k + 1, 2}$

Daebeom Choi

In this work, we study a family of vector bundles on the moduli space of curves constructed from representations of $Vir_{2 k + 1, 2}$ , a family of vertex operator algebras deri…
