question about shape preservation of a discrete function please
Hi all, I have a discrete function g: X -> R, which is "convex" in the sense that I piecewiselinearly interpolate the function on the grid pionts in X, I got a convex function on a convex set X'. Suppose the domain X is a finite set (e.g. a bounded subset of Z^n), I use piecewise linear interpolation to constru... 11 Jun 2010 15:55

Question about the Goldbach conjecture
What is the first even number larger than 6 that cannot be written as the sum of two primes with at least one of the primes 6 less than another prime. This is equivalent to the Goldbach conjecture. I didn't find any from 8 to 300. ... 14 Jun 2010 19:37

JSH: Posting realities, residues result
I've been fascinated by the response to my posting of a general result for solving quadratic residues because of the elephant in the room NOT mentioned, which is that it is mod N, whereas mathematicians usually MUST use mod p, where p is a prime. That's important for factoring as if N is a composite then with k^2... 15 Jun 2010 18:46

Stones on a grid puzzle
This for me is an unsolved puzzle. Start with a 9-by-9 grid. Place any number of black stones and whites stone on the squares of the grid so that each square has exactly one stone. For a given row of the grid, take the lengths of the runs of black stones and white stones and multiply these lengths. (By "run",... 9 Jul 2010 12:46

Boundedness in L^p[0,1]
Let X=[0,1]. Suppose a sequence {f_n} is in L^p and a function f is in L^p. If f_n converges weakly to f in some L^{p_1} with p_1 less than p, does {f_n} they converge weakly in L^p? ... 11 Jun 2010 11:27

EINSTEINIANS AS MARAUDERS
High priests in Einsteiniana have always known that Einstein's 1905 light postulate is false, that its antithesis given by Newton's emission theory of light is true and that Einstein's 1954 confession announcing the death of physics was quite reasonable: http://www.prospect-magazine.co.uk/article_details.php?id=5... 19 Jun 2010 02:40
