    Why would anyone ask a question about partially ordered set (that is what mathematicians mean by poset) if he/she does not know the basic definitions.
    Can you define partially ordered sets? If not, why ask?

    Dear Friend,
    be pretty sure of that If I knew mathematics like you do, I wouldn't be here asking questions. I don't think "ask a question" is something that I should be ashamed of, since this place is created for that reason.
    you are here to help people with your abilities in mathematics or you are here to tease people for what they do not know and they try to learn???
    If you see that I don't know the basic definitions and I need them to understand my question, then explain and inspire a user to go and learn more, instead of teasing him/her for not knowing a concept...
