I have found a conjecture in an research article of number theory, which is not well known but very reasonable. Let me be clear that, there is no counter-example that vote down the conjecture, rather, its trueness has been proved in some special situation so far. I need this conjecture to develop a $tool$ in order to write an research article. Unfortunately, I am unable to prove the conjecture as of now. May be others can prove it after some time.

**My question:** 

Is it a reasonable way to write an research article assuming truth of the conjecture ?
