Perhaps you should try some spelling variations:
"stochastic differences equations" » "stochastic difference equations", "stochastic inference equations", "stochastic differentials equations", "stochastic difference equation", "stochastic differential equations"
"stochastic differential equation" » "stochastic differential equations", "stochastic difference equations"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("stochastic differential equation") OR ("stochastic differences equations")).
• Removing quotes may allow a broader search: (( stochastic differential equation ) or ( stochastic differences equations )).
• Adding a wildcard symbol may retrieve word variants: (("stochastic differential equation") or ("stochastic differences equations"))*.
