报告摘要:  Lagrange's four-square theorem asserts that any natural number can be written as x2+y2+z2+w2 with x,y,z,w integers. In this talk we introduce recent progress on the speaker's1-3-5-Conjecture which asserts that any nonnegative integer can be written as the sum of squares of four nonnegative integers x,y,z,w such that x+3y+5z is a square. We will also mention related techniques and results on partitions of integers.
