Bakalaureusetöös vaadeldakse Banachi ruumis tuumaoperaatoril defineeritud jälge. Töös uuritakse, millistes Banachi ruumides on iga summeeruvate omaväärtustega tuumaoperaatori jälg võrdne tema omaväärtuste summaga. Tuuakse näide sellisest Banachi ruumist, kus see tingimus on täidetud, aga mis ei ole Hilberti ruum. Lisaks näidatakse, et sellistel ruumidel on päranduv aproksimatsiooniomadus. Töö põhineb peamiselt W. B. Johnsoni ja A. Szankowski artiklil The trace formula in Banach spaces (Israel J. Math. 203, 2014).
