On the Diophantine Equation 2^a3^b + 2^c3^d = 2^e3^f + 2^g3^h
Roger Tian
This paper is a continuation of [1], in which I studied Harvey Friedman's problem of whether the function f(x,y) = x^2 + y^3 satisfies any identities; however, no knowledge of [1]…

Identities of the Function f(x,y) = x^2 + y^3
Roger Tian
Harvey Friedman asked in 1986 whether the function f(x,y) = x^2 + y^3 on the real plane R^2 satisfies any identities; examples of identities are commutativity and associativity. To…
