Perhaps you should try some spelling variations:
"problemas of induction" » "problemas of reduction", "problemas of infection", "problemas of introduction", "problemaas of induction", "problemsas of induction"
"problem of induccion" » "problema of induccion", "problems of induccion", "problem of introduccion"
"problem of reduccion" » "problema of reduccion", "problems of reduccion", "problem of produccion", "problem of traduccion", "problem of educacion"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("problemas of induction") OR ((("problem of induccion") OR ("problem of reduccion"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"problemas of induction\") OR (((\"problem of induccion\") OR (\"problem of reduccion\"))))".
• Removing quotes may allow a broader search: (( problemas of induction ) OR ((( problem of induccion ) OR ( problem of reduccion )))).
• Adding a wildcard symbol may retrieve word variants: (("problemas of induction") OR ((("problem of induccion") OR ("problem of reduccion"))))*.
