    I discovered today a new category (related to topology):

    See this math.SE question.

    Am I the first who has described this category or have I come again with somebody other's discovery?

    Looks like just the full subcategory of Lax(2,Pos)Lax(2,Pos) on the endomorphisms.

    Where to read about "Lax"? (preferably open access on the Web)

    lax natural transformation (there I think the notation used is 2Cat lax(−,−)2Cat_{lax}(-,-)).

    I think the inequality specified in the question means we want oplax transformations (in the terminology of the linked article).
