Introduction Let N(t) be the number of integer lattice points in a disk of radius tcentered at the origin. Thus N(t) = P n≤t2 r(n) where r(n) is the number of ways of writing n= x2 + y2 as a sum of two squares. As is well known, N(t) is asymptotic to the area πt2 of the disk. bjp seats in lok sabha 2022
