In algebra there are many objects which are standard, for example Standard Young Tableaux, Standard Monomials, Standard Bitableaux. We adopt a point of view that these standard objects are really non-nesting, and we find their non-crossing counterparts.15 pages, 12 figures; some changes in presentation made, a subsection addedCombinatorics05E10Non-Crossing Tableauxtext
