Perhaps you should try some spelling variations:
"several complex variables and analytical surfaces" » "several complex variables and analytical surface", "several complex variables and analytic surfaces", "several complex variables and analytical services"
"several complex variables and analytical spaces" » "several complex variables and analyticity spaces", "several complex variables and analytic space", "several complex variables and analytical scale"

Try widening your search to All Fields.

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: (((("several complex variables and analytical spaces") OR ("several complex variables and analytic spaces"))) OR ("several complex variables and analytical surfaces")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"several complex variables and analytical spaces\") OR (\"several complex variables and analytic spaces\"))) or (\"several complex variables and analytical surfaces\"))".
• Removing quotes may allow a broader search: (((( several complex variables and analytical spaces ) OR ( several complex variables and analytic spaces ))) or ( several complex variables and analytical surfaces )).
• Adding a wildcard symbol may retrieve word variants: (((("several complex variables and analytical spaces") OR ("several complex variables and analytic spaces"))) or ("several complex variables and analytical surfaces"))*.
