  5. Decidability of first-order theories of the real numbers

    en.wikipedia.org/wiki/Decidability_of_first...

    The theory of real closed fields is the theory in which the primitive operations are multiplication and addition; this implies that, in this theory, the only numbers that can be defined are the real algebraic numbers. As proven by Tarski, this theory is decidable; see Tarski–Seidenberg theorem and Quantifier elimination.

  6. Entscheidungsproblem - Wikipedia

    For example, the Bernays–Schönfinkel class, [] =, is the class of first-order formulas with quantifier prefix , equality symbols, and no function symbols. For example, Turing's 1936 paper (p. 263) observed that since the halting problem for each Turing machine is equivalent to a first-order logical formula of form , the problem () is ...

    The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ambiguous. Here, "functional flow" pertains to the sequencing of operations, with "flow" arrows expressing dependence on the success of prior operations.
