摘要：

The components of the renormalized quantum stress tensor for a massive vector field in the spacetime of a pointlike global monopole are determined analytically in the Schwinger-DeWitt approximation. The general results are employed to investigate the pointwise energy conditions for the quantized matter field and it is shown that they are all violated by the massive vector field.
