I have to talk into a paper of mine about a new proposed operator: do you think it is of any use to talk about it within the introduction? My problem is that, by doing so, maybe a reader/reviewer could arise more problems than the ones he could motivate by reading the whole description later on the paper. On the other hand an example of such operator within the introduction helps the reader/reviewer to better understand the problem this new operator tries to solve. Another problem is that, if the example is too simple, then he could think that more difficult tasks could not be solved by this specific operator. Thanks in advance!
