More specifically, folk mathematics, or mathematical folklore, is the body of theorems, definitions, proofs, facts or techniques that circulate among mathematicians by word of mouth, but have not yet appeared in print, either in books or in scholarly journals.
On the other hand, MIT economist Franklin Fisher has noted that the folk theorem is not a positive theory. [13] In considering, for instance, oligopoly behavior, the folk theorem does not tell the economist what firms will do, but rather that cost and demand functions are not sufficient for a general theory of oligopoly, and the economists must ...
In folkloristics, morphology is the study of the structure of folklore and fairy tales.. Some pioneering work in this field was begun in the nineteenth century, such as Marian Roalfe Cox's work on Cinderella, Cinderella: Three Hundred and Forty-Five Variants of Cinderella, Catskin and, Cap O' Rushes, Abstracted and Tabulated with a Discussion of Medieval Analogues and Notes.
Folk theorem or folklore theorem may refer to: Mathematical folklore, theorems that are widely known to mathematicians but cannot be traced back to an individual; Folk theorem (game theory), a general feasibility theorem; Ethnomathematics, the study of the relationship between mathematics and culture
The Aarne–Thompson–Uther Index (ATU Index) is a catalogue of folktale types used in folklore studies.The ATU index is the product of a series of revisions and expansions by an international group of scholars: Originally published in German by Finnish folklorist Antti Aarne (1910), [1] the index was translated into English, revised, and expanded by American folklorist Stith Thompson (1928 ...
The motif-index and the ATU indices are regarded as standard tools in the study of folklore. For example, folklorist Mary Beth Stein said that, "Together with Thompson's six-volume Motif-Index of Folk-Literature, with which it is cross-indexed, The Types of Folktale constitutes the most important reference work and research tool for comparative folk-tale analysis. [1]
Folk memory, also known as folklore or myths, refers to past events that have been passed orally from generation to generation. The events described by the memories may date back hundreds, thousands, or even tens of thousands of years and often have a local significance.
In model theory, a branch of mathematical logic, the diagram of a structure is a simple but powerful concept for proving useful properties of a theory, for example the amalgamation property and the joint embedding property, among others.
