U ovom radu istražujemo mogućnost primjene tradicionalnih i suvremenih estetičkih teorija na logičko-matematičke dokaze, s ciljem boljeg razumijevanja intuitivnog pojma matematičke ljepote. Ovo je neformalan pojam koji zauzima središnje mjesto u radu logičara i matematičara i može se smatrati njihovom glavnom motivacijom. U ovom radu pokušavamo definirati pojmove vezane uz matematičku ljepotu, odnosno ljepotu u matematičkim dokazima, da bismo postavili temelje za preciznu definiciju matematičke ljepote koju bismo dobili preko detaljnog anketiranja logičara i matematičara, a što bismo proveli u odvojenom radu. Ovaj rad donosi važne rezultate za izradu te ankete.; In this paper, we explore the possibility of applying traditional and modern aesthetical theories to logical and mathematical proofs, with the goal of better understanding the intuitive concept of mathematical beauty. This informal concept takes a central role in the work of logicians and mathematicians and can be thought of as their main motivation. In the present paper, we try to define concepts connected to mathematical beauty or beauty in mathematical proofs, so that we may lay the foundations for a more precise definition of mathematical beauty which would be obtained through a detailed survey among logicians and mathematicians, presented in a future paper. The present paper brings crucial results to be used for constructing the survey.
