Query: Simple stably projectionless C*-algebras with generalized tracial rank
  one   We study a class of stably projectionless simple C*-algebras which may be
viewed as having generalized tracial rank one in analogy with the unital case.
Some structural question concerning these simple C*-algebras are studied. The
paper also serves as a technical support for the classification of separable
stably projectionless simple amenable Jiang-Su stable C*-algebras.
