Query: Some remarks on quasi generalized CR-null geometry in indefinite nearly
  cosymplectic manifolds   In [21], the authors initiated the study of quasi generalized CR (QGCR)-null
submanifolds. In this paper, attention is drawn to some distributions on
ascreen QGCR-null submanifolds in an indefinite nearly cosymplectic manifold.
We characterize totally umbilical and irrotational ascreen QGCR-null
submanifolds. We finally discuss the geometric effects of geodesity conditions
on such submanifold.
