**Difference equations in normed spaces: Stability and oscillations**

Many difficulties for partial distinction and integro-difference equations will be written as distinction equations in a normed house. This ebook is dedicated to linear and nonlinear distinction equations in a normed house. Our objective during this monograph is to start up systematic investigations of the worldwide habit of ideas of distinction equations in a normed house.
