We study the algebraic closure construction for metric structures in the setting of continuous first order logic. We give several characterizations of algebraicity, and we prove basic properties analogous to ones that algebraic closure satisfies in classical first order logic.
Key words: Continuous logic, metric structures, algebraic closure.
Estudiamos la construcción de la clausura algebraica para estructuras métricas en el contexto de la lógica continua de primer orden. Damos varias caracterizaciones de algebricidad y probamos propiedades básicas análogas a aquellas que satisface la clausura algebraica en lógica clásica de primer orden.
Palabras clave: Lógica continua, estructuras métricas, clausura algebraica.
