Binomial coefficients and the ring of p-adic integers
Zhi-Wei Sun, Wei Zhang
Let k>1 be an integer and let p be a prime. We show that if or (with 2q<p) for some a=1,2,..., then the set {\binom{n}{k}: n=0,1,2,...} is dense in the r…

On sums of primes and triangular numbers
Zhi-Wei Sun
We study whether sufficiently large integers can be written in the form cp+T_x, where p is either zero or a prime congruent to r mod d, and T_x=x(x+1)/2 is a triangular number. We…
