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

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 differential equations") OR ("stochastic differences equations")))).
• Removing quotes may allow a broader search: (( stochastic differential equation ) or ((( stochastic differential equations ) or ( stochastic differences equations )))).
• Adding a wildcard symbol may retrieve word variants: (("stochastic differential equation") or ((("stochastic differential equations") or ("stochastic differences equations"))))*.
