For in the field of real variable Marcinkiewicz had exceptionally strong intuition and technique, and the results he obtained in the theory of conjugate functions, had they been extended to functions of several variables might have given (as we see clearly now) a strong push to the theory of partial differential equations.
Para sa larangan ng real variable Marcinkiewicz had iba strong kawatasan at pamamaraan, at ang mga resulta niya nakuha sa teorya ng ibanghay function, nagkaroon sila ay pinalawig sa pag-andar ng ilang mga variable na maaaring magkaroon ng ibinigay na (bilang namin makita ang malinaw na ngayon) ng isang malakas na tulak sa ng teorya ng bahagyang kaugalian equation.
