Perhaps you should try some spelling variations:
"stochastic differential equation" » "stochastic differential equations", "stochastic difference equations"
"stochastic difference equationss" » "stochastic difference equations", "stochastic difference equation", "stochastic differences 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 difference equationss")).
• Removing quotes may allow a broader search: (( stochastic differential equation ) or ( stochastic difference equationss )).
• Adding a wildcard symbol may retrieve word variants: (("stochastic differential equation") or ("stochastic difference equationss"))*.
