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