As a consequence of Matiyasevich’s refutation of Hilbert’s 10th problem, it can be proved that there does not exist a general algorithm for solving a general quartic Diophantine equation. However, the algorithm for constructing such an unsolvable quartic Diophantine equation can require arbitrarily many variables Matiyasevich As a part of the study of Waring’s problemit is known that every positive integer is a sum of no more than 19 positive biquadratesthat every “sufficiently large” integer is a sum of no more than 16 positive biquadratesand that every integer is a sum of at most 10 signed biquadrates ; although it is not known if 10 can be reduced to 9.

The first few numbers which are a sum of four fourth powers equations are,In fact, the equations.

The only number of the form. Let the notation stand for the equation consisting of a sum of th powers being equal to a sum of th powers. InEuler proposed that the 4. This assertion is known as the Euler quartic conjecture.

Ward showed there were no solutions forwhich was subsequently improved to by Lander et al. However, the Euler quartic conjecture was disproved in by N.

Elkies, who, using a geometric construction, found. InRoger Frye found.

Another solution was found by Allan MacLeod in. It is not known if there is a parametric solution. In contrast, there are many solutions to the equation. NorriePattersonLeechBrudnoLander et al.

Additional solution are given by Wroblewski. It was not known if there was a parametric solution Guyp.

Their solution makes extensive use of elliptic curve theory and the special solution,; due to Brudnowhich satisfies.

Berndt and Bhargava and Berndtpp. These are also given by Dicksonp. Other solutions are given by FauquembergueHaldemanand Martin Similar quadratic form parametrizations given by Ramanujan can be found using the identity. The situation is then reduced to finding solutions towhere is the sum and difference of a number of fourth powers. As an example, given. The first few primitive solutions are.

General but incomplete solutions are given by. Similar examples can be found in Martin Haldeman gives general formulas for and equations. Bhargava’s theorem is a general identity which gives the above equations as a special case, and may have been the route by which Ramanujan proceeded. Another identity due to Ramanujan is. Additional solutions are,and,E.
