在这个简短的注记中,我们考虑了在紧Kahler流形上确定伪有效锥边界附近体积函数的渐近性的问题。我们在许多情况下解决了这个问题--特别地,我们证明了体积函数在数值维为零的伪有效类附近的小扰动下表现为多项式。
In this short note, we consider the question of determining the asymptotics of the volume function near the boundary of the pseudoeffective cone on compact Kahler manifolds. We solve the question in a number of cases -- in particular, we show that the volume function behaves polynomially under small perturbations near pseudoeffective classes with numerical dimension zero.
