| Nov 13, 2015 at 23:42 | comment | added | Ran G. | @DavidRicherby, this is pretending innocence. The question asks several different questions (union, intersection, etc.), each of them where answered separately, and can easily be found using the search (search "regular" and "intersection" for instance). I'm not sure why you are defending it so strongly, while it is a clear duplicate of multiple questions that keep popping here ever semester. If you wish to keep arguing on technicalities - be my guest, I'm not going to play this game. | |
| Nov 13, 2015 at 23:27 | comment | added | David Richerby | @RanG. The first of those questions asks about the intersection of a specific regular language with a specific non-regular language. The second is completely unrelated and I honestly don't know why you're even mentioning it. The third covers only intersection and my answer to it isn't particularly general. None of this justifies your shouty boldface accusations or your claim that the question has been asked "a gazillion times." Where's the dupe? | |
| Nov 13, 2015 at 22:05 | comment | added | Ran G. | @DavidRicherby see for instance, q/35644, and also related (for kleene star) q/28536, and almost similar question yet when one of the languages is decidable, q/33822, etc., and those are only questions that YOU have answered. Searching for duplicates takes time, which the OP should have invested before posting. Of course, I'm not telling you what to do with your time – if you feel the need to support and answer these kind of questions this is definitely your right. | |

| Nov 13, 2015 at 17:37 | comment | added | advocateofnone | How did you try proving ? For starters you could come up with examples. eg let $L_1=\{a^ib^i | i \ge 0 \}$ and $L_2=\{\epsilon\}$. What can you say about $L_1$,$L_2$ and their intersection ? | |
