Query: From AdS to Schr\"odinger/Lifshitz dual space-times without or with
  hyperscaling violation   It is observed that the (intersecting) branes of M/string theory, which are
known to give AdS geometry (directly or upto a conformal transformation) in the
near horizon limit, do also lead to Schr\" odinger/Lifshitz dual space-times
(without or with hyperscaling violation) upon using appropriate solution
generating transformation and dimensional reduction. We show that the dynamical
exponents of the Schr\" odinger and the Lifshitz space-times obtained in this
way always add upto 2. We illustrate this by several examples, including M2-,
M5-branes of M-theory and D$(p+1)$-branes ($p\neq 4$, since in this case the
near horizon limit does not give AdS geometry) of string theory as well as many
of their intersecting solutions. The Schr\" odinger space-time can be obtained
by the standard wave generating technique along one of the brane directions
(for single brane) or one of the common brane directions (for intersecting
branes) and then interchanging the light-cone coordinates by double Wick
rotations, whereas, the Lifshitz space-time can be obtained by dimensionally
reducing (for M-theory) along the wave direction or taking T-duality (for
string theory) along the same direction. We thus obtain Schr\" odinger/Lifshitz
dual space-times without or with hyperscaling violation from the same M/string
theory solutions and they preserve some fraction of the supersymmetry.
