An inaccessible cardinal is a cardinal number which cannot be expressed in terms of a smaller number of smaller cardinals.

The study of number fields by embedding them in a local field is called local class field theory. Information about an equation in a local field may give information about ...

A game in which each player has a finite number of moves and a finite number of choices at each move.

A polygonal diagonal is a line segment connecting two nonadjacent polygon vertices of a polygon. The number of ways a fixed convex n-gon can be divided into triangles by ...

B_(p+k)=B_k+B_(k+1) (mod p), when p is prime and B_n is a Bell number.

Calculus of variations can be used to find the curve from a point (x_1,y_1) to a point (x_2,y_2) which, when revolved around the x-axis, yields a surface of smallest surface ...

An integer used to generate a digitaddition. A number can have more than one generator. If a number has no generator, it is called a self number.

In any tree, the number of dissimilar points minus the number of dissimilar lines plus the number of symmetry lines equals 1.

A dozen dozen, or the square number 144.

If p and q are distinct odd primes, then the quadratic reciprocity theorem states that the congruences x^2=q (mod p) x^2=p (mod q) (1) are both solvable or both unsolvable ...
