In the mathematics of sums of powers, it is an open problem to characterize the numbers that can be expressed as a sum of three cubes of integers, allowing both positive and negative cubes in the sum. A necessary condition for $${\displaystyle n}$$ to equal such a sum is that See more A nontrivial representation of 0 as a sum of three cubes would give a counterexample to Fermat's Last Theorem for the exponent three, as one of the three cubes would have the opposite sign as the other two and its … See more Since 1955, and starting with the instigation of Mordell, many authors have implemented computational searches for these representations. Elsenhans & Jahnel (2009) used a method of Noam Elkies (2000) involving lattice reduction to search for all solutions to the See more A variant of this problem related to Waring's problem asks for representations as sums of three cubes of non-negative integers. In the 19th century, Carl Gustav Jacob Jacobi and … See more • Sum of four cubes problem, whether every integer is a sum of four cubes • Euler's sum of powers conjecture § k = 3, relating to cubes … See more The sums of three cubes problem has been popularized in recent years by Brady Haran, creator of the YouTube channel Numberphile, … See more In 1992, Roger Heath-Brown conjectured that every $${\displaystyle n}$$ unequal to 4 or 5 modulo 9 has infinitely many representations as sums of three cubes. The case $${\displaystyle n=33}$$ of this problem was used by Bjorn Poonen as the opening example in … See more • Solutions of n = x + y + z for 0 ≤ n ≤ 99, Hisanori Mishima • threecubes, Daniel J.
