ON THE INDEFINITE EQUATIONS

x~3+1=Dy~2Ni Guyan(National University of Defence Technology)  
In this paper, we have got that the indefinite equations x 3+1=Dy 2 have nontrivial integer solutions only when D=7,14,35,38,57,65,86, and proved that it has not nontrivial integer solutions if D=91, where 0D100, squarefree and is divisible by primes of the form 6k+1.
