    Indeed, questions 1-26 follow generating function through further examples. [4]: 23 Whole areas of mathematics are developed in this way. [1]: 55 Substantial additions were made in the English translation (published in 1972 and 1976), including new sections and back-references to Pólya's other works on problem solving. [4]: 24–25

    First, you have to understand the problem. [2] After understanding, make a plan. [3] Carry out the plan. [4] Look back on your work. [5] How could it be better? If this technique fails, Pólya advises: [6] "If you cannot solve the proposed problem, try to solve first some related problem. Could you imagine a more accessible related problem?"

    en.wikipedia.org/wiki/Jordan–Pólya_number

    In mathematics, the Jordan–Pólya numbers are the numbers that can be obtained by multiplying together one or more factorials, not required to be distinct from each other. For instance, 480 {\displaystyle 480} is a Jordan–Pólya number because 480 = 2 ! ⋅ 2 ! ⋅ 5 ! {\displaystyle 480=2!\cdot 2!\cdot 5!} .

  5. Problem Solving Through Recreational Mathematics - Wikipedia

    en.wikipedia.org/wiki/Problem_Solving_Through...

    Problem Solving Through Recreational Mathematics is based on mathematics courses taught by the authors, who were both mathematics professors at Temple University. [1] [2] It follows a principle in mathematics education popularized by George Pólya, of focusing on techniques for mathematical problem solving, motivated by the idea that by doing mathematics rather than being told about its ...

  6. Mathematics and Plausible Reasoning - Wikipedia

    en.wikipedia.org/wiki/Mathematics_and_plausible...

    Mathematics and Plausible Reasoning is a two-volume book by the mathematician George Pólya describing various methods for being a good guesser of new mathematical results. [ 1 ] [ 2 ] In the Preface to Volume 1 of the book Pólya exhorts all interested students of mathematics thus: "Certainly, let us learn proving, but also let us learn guessing."

  7. Pólya enumeration theorem - Wikipedia

    en.wikipedia.org/wiki/Pólya_enumeration_theorem

    The Polya enumeration theorem translates the recursive structure of rooted ternary trees into a functional equation for the generating function F(t) of rooted ternary trees by number of nodes. This is achieved by "coloring" the three children with rooted ternary trees, weighted by node number, so that the color generating function is given by f ...

  8. Pólya conjecture - Wikipedia

    en.wikipedia.org/wiki/Pólya_conjecture

    The Pólya conjecture states that for any n > 1, if the natural numbers less than or equal to n (excluding 0) are partitioned into those with an odd number of prime factors and those with an even number of prime factors, then the former set has at least as many members as the latter set. Repeated prime factors are counted repeatedly; for ...

  9. Pólya–Szegő inequality - Wikipedia

    en.wikipedia.org/wiki/Pólya–Szegő_inequality

    The proof goes by restating the problem as a minimization of the Rayleigh quotient. [1] The isoperimetric inequality can be deduced from the Pólya–Szegő inequality with =. The optimal constant in the Sobolev inequality can be obtained by combining the Pólya–Szegő inequality with some integral inequalities. [2] [3]
