  3. Catalan's conjecture - Wikipedia

    en.wikipedia.org/wiki/Catalan's_conjecture

    [1] [2] The integers 2 3 and 3 2 are two perfect powers (that is, powers of exponent higher than one) of natural numbers whose values (8 and 9, respectively) are consecutive. The theorem states that this is the only case of two consecutive perfect powers.

  4. Cyclic quadrilateral - Wikipedia

    en.wikipedia.org/wiki/Cyclic_quadrilateral

    In spherical geometry, a spherical quadrilateral formed from four intersecting greater circles is cyclic if and only if the summations of the opposite angles are equal, i.e., α + γ = β + δ for consecutive angles α, β, γ, δ of the quadrilateral. [30] One direction of this theorem was proved by Anders Johan Lexell in 1782. [31]

  5. Transversal (geometry) - Wikipedia

    In this case, all 8 angles are right angles [1] When the lines are parallel, a case that is often considered, a transversal produces several congruent supplementary angles. Some of these angle pairs have specific names and are discussed below: corresponding angles, alternate angles, and consecutive angles. [2] [3]: Art. 87

  8. Tijdeman's theorem - Wikipedia

    en.wikipedia.org/wiki/Tijdeman's_theorem

    The theorem was proven by Dutch number theorist Robert Tijdeman in 1976, [3] making use of Baker's method in transcendental number theory to give an effective upper bound for x,y,m,n. Michel Langevin computed a value of exp exp exp exp 730 for the bound. [1] [4] [5]

  9. Bar induction - Wikipedia

    en.wikipedia.org/wiki/Bar_induction

    An additional schema of bar induction was originally given as a theorem by Brouwer (1975) containing no "extra" restriction on under the name The Bar Theorem. However, the proof for this theorem was erroneous, and unrestricted bar induction is not considered to be intuitionistically valid (see Dummett 1977 pp 94–104 for a summary of why this ...
