The asymptotic generalized Fermat conjecture

About 6 years old · traced to

Let KK be a number field, and let A,B,CA,B,C be non-zero elements of OK\mathcal{O}_K. Let Ω\Omega be the subgroup of roots of unity inside OK×\mathcal{O}_K^{\times}. Suppose

Aω1+Bω2+Cω3≠0A\omega_1+B\omega_2+C\omega_3\neq 0

for any ω1,ω2,ω3∈Ω\omega_1,\omega_2,\omega_3\in\Omega. A solution (x,y,z)∈K3(x,y,z)\in K^3 of the Fermat equation

Axp+Byp+Czp=0Ax^p+By^p+Cz^p=0

is trivial when it is one of the solutions excluded by the conjecture's usual notion of triviality. Asymptotic generalized Fermat conjecture. There exists a constant B(K,A,B,C)\mathcal{B}(K,A,B,C), depending only on K,A,B,CK,A,B,C, such that for all primes p>B(K,A,B,C)p>\mathcal{B}(K,A,B,C), the only solutions are the trivial solutions. This conjecture seeks effective uniform bounds for generalized Fermat equations over number fields; despite progress toward AGFC, obtaining effective bounds B(K,A,B,C)\mathcal{B}(K,A,B,C) remains open.
