... A k-superperfect number n is an integer such that σ k (n) = 2n, where σ k (x) is the iterated sum of divisors function. For example, 16 is 2-superperfect since its divisors add up to 31, and in turn the divisors of 31 add up to 32, which is twice 16. At first Suryanarayana only considered 2-superper ...

What is Creative Problem Solving in Mathematics?
... To promote the creative problem solving in mathematics, I recommend some critical points discovered through my experiences of gifted education in mathematics for 10 years. Firstly, it is important to make a reasonable deduction by such creative hypothesis as 17C Korean mathematicians. Some 5th grade ...

... In radio-astronomy circles, it is sometimes jokingly speculated whether it is possible to place infinitely many in-phase, nonaligned antennas in a plane (say, vertical dipoles in a horizontal plane). Geometrically, this means placing infinitely many nonaligned points in R2, with integral pairwise di ...
