21Dominance-based rough set approach — (DRSA) is an extension of rough set theory for multi criteria decision analysis (MCDA), introduced by Greco, Matarazzo and Słowiński. [1][2][3] The main change comparing to the classical rough sets is the substitution of the indiscernibility… …
22Autocatalytic set — An autocatalytic set is a collection of entities, each of which can be created catalytically by other entities within the set, such that as a whole, the set is able to catalyze its own production. In this way the set as a whole is said to be… …
23Typical set — In information theory, the typical set is a set of sequences whose probability is close to two raised to the negative power of the entropy of their source distribution. That this set has total probability close to one is a consequence of the… …
24Landau set — In voting systems, the Landau set (or uncovered set, or Fishburn set) is the set of candidates x such that for every other candidate y , there is some candidate z (possibly the same as x , but distinct from y ) such that y is not preferred to x… …
25Tree (set theory) — In set theory, a tree is a partially ordered set (poset) ( T …
26Wave front set — In mathematical analysis, more precisely in microlocal analysis, the wave front (set) WF( f ) characterizes the singularities of a generalized function f , not only in space, but more precisely also with respect to its Fourier transform at each… …
27Evolutionarily stable set — In game theory an evolutionarily stable set, (sometimes evolutionary stable sets) (ES set) is a set of strategies, which score equally against each other, each of which would be an evolutionarily stable strategy (ESS) were it not for the other… …
28Principles of Theoretical Logic — Principles of Mathematical Logic is the 1950 American translation of the 1938 second edition of David Hilbert s and Wilhelm Ackermann s classic text Grundzüge der theoretischen Logik , on elementary mathematical logic. The 1928 first edition… …
29mathematics, foundations of — Scientific inquiry into the nature of mathematical theories and the scope of mathematical methods. It began with Euclid s Elements as an inquiry into the logical and philosophical basis of mathematics in essence, whether the axioms of any system… …
30logic, philosophy of — Philosophical study of the nature and scope of logic. Examples of questions raised in the philosophy of logic are: In virtue of what features of reality are the laws of logic true? ; How do we know the truths of logic? ; and Could the laws of… …
