I have list of two or more natural numbers.l=(k1::k2::t).These ks may be same or different because i have no hypothesis related to this.Only available information is H2:z1=k1 H3:z2=k2. z1=z2 is possible? (only when k1=k2 ,i have no information about this. To avid this i have to add no duplication )

you shoudl do Absurd (k1 = k2). One subgoal is solved by the fact that there is no duplication, the second one because of available information.
