Hyperarithmetic numerals

Abstract

Within the framework of computable infinitary continuous logic, we develop a system of hyperarithmetic numerals. These numerals are infinitary sentences in a metric language LL that have the same truth value in every interpretation of LL. We prove that every hyperarithmetic real can be represented by a hyperarithmetic numeral at the same level of complexity.
