Perhaps you should try some spelling variations:
"stochastic differential equation" » "stochastic difference equations"
"stochastic differential equations" » "stochastic difference equationss"
"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 differential equations") OR ("stochastic difference equationss"))) OR ("stochastic difference equationss")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"stochastic differential equation\") or (((((\"stochastic differential equations\") OR (\"stochastic difference equationss\"))) or (\"stochastic difference equationss\"))))".
• Removing quotes may allow a broader search: (( stochastic differential equation ) or ((((( stochastic differential equations ) OR ( stochastic difference equationss ))) or ( stochastic difference equationss )))).
• Adding a wildcard symbol may retrieve word variants: (("stochastic differential equation") or ((((("stochastic differential equations") OR ("stochastic difference equationss"))) or ("stochastic difference equationss"))))*.
