Perhaps you should try some spelling variations:
"stochastic different evaluations" » "stochastic different valuations", "stochastic different evolutions", "stochastic different calculations", "stochastic differentials evaluations", "stochasjic differential evaluations", "stochastic interest evaluations"
"stochastic differential equations" » "stochastic differentialsial equations", "stochasjic differentialial equations", "stochastic interestial 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 difference equations") OR ("stochastic different evaluations"))) OR ("stochastic differential equations")).
• Removing quotes may allow a broader search: (((( stochastic difference equations ) or ( stochastic different evaluations ))) or ( stochastic differential equations )).
• Adding a wildcard symbol may retrieve word variants: (((("stochastic difference equations") or ("stochastic different evaluations"))) or ("stochastic differential equations"))*.
