Twodimensional semantics: Twodimensional are semantics that take into account both the properties of a situation described by a statement and the properties of the utterance situation (which need not be identical with the described situation). For example, the statement that one is at location A, B or C is true when it is uttered at location A, B or C (diagonalization). Statements of a particular form are always true, e.g. "I am here now". In this case, the entire two-dimensional matrix is assigned the value "true". Two-dimensional semantics go back to D. Kaplan (D. Kaplan, Demonstratives, in Perry & Wettstein (Eds.) Themes from Kaplan, Oxford, 1989, pp. 481-563). See also context/context dependency, diagonalization, diagonal propositions, A-intensions, C-intensions, Stalnaker intensions, character, content.

Double indexing/double index/possible worlds/counterfactual conditional/Lewis: Counterfactual conditionals are contingent in general - so we need double indexing - i.e. that certain phrases are not absolutely true/false - but in relation to a world j - Let F be a special sentence which is true in j relative to i iff j f (A, i) (similar world) . - then F A > C is true in j relative to i, if j belongs to f (A, i), C is true in j ( If..., if...).
Definition operator \$/spelling dollars for death Cross/Lewis: \$ B is true in i relative to j iff B is true in i relative to i itself.
Definition counterfactual conditional/Lewis: - A >> C = definition \$ N (F A > C) - so that we have a choice function brought into the object language.
