Abstract

It was conjectured by Emil Artin in the 1930's that every dd-form F(x1,x2,F(x_1, x_2, \ldots,xn), x_n) over the pp-adic field in more than d2d^2 variables has a solution that is not (0,0,,0)(0, 0, \cdots, 0) (non-trivial solution) over the pp-adic field. This is true for d=2d=2 and d=3d=3. However, many counterexamples for d4d \geq 4 were later discovered. The major types of counterexamples are Terjanian Type and Arkhipov-Kara\v{c}uba Type. The degrees of all known counterexamples, however, are divisible by p1p-1, which means that they are even for all odd primes. In this article we apply modifications to the known Arkhipov-Kara\v{c}uba Type counterexamples to construct counterexamples with odd degrees that are divisible by p12\frac{p-1}2 for all primes greater than 33 and congruent to 33 modulo 44 and then propose some ideas about increasing the number of variables in the counterexamples.

There is an error with equation (5), leading to a breakdown of the arguments in the third section
