Abstract interpretation is an excellent tool for designing complete dataflow analyses [6]. Existential quantification is an excellent tool for designing precise dataflow analyses. However, these two tools are difficult to combine. Abstract interpretation requires algorithms for deciding subtypes and constructing joins. This is problematic for existential quantification because simply subtyping ...

We prove that, building upon the universal-existential orthogonality-based axiom system for metric planes presented in [28], one can provide universal-existential axiom systems – expressed solely in terms of the ternary predicate I, with I(abc) standing for ‘ab is congruent to ac’, which Pieri has introduced 100 years ago – for metric planes, for absolute geometry with the circle axiom, for Euc...

Authors of American psychology textbooks habitually refer to the “existential-humanistic” or “humanistic-existential” approach to treatment, while therapists in the UK and Europe say that this usage is inaccurate, and that the differences between the existential and humanistic approaches outweigh their similarities. To assess the merit of these competing claims, we must distinguish between lite...

As is well-known a language of finite words, considered as labeled linear orders, is definable in monadic second-order logic (MSO) iff it is definable in the existential fragment of MSO, that is the quantifier alternation hierarchy collapses. Even more, it does not make a difference if we consider existential MSO over a linear order or a successor relation only. In this note we show that somewh...
