QUÉ SIGNIFICA CARDINALITY EN INGLÉS
Cardinalidad
En matemáticas, la cardinalidad de un conjunto es una medida del "número de elementos del conjunto". Por ejemplo, el conjunto A = contiene 3 elementos y, por tanto, A tiene una cardinalidad de 3. Hay dos aproximaciones a la cardinalidad: una que compara conjuntos directamente usando biyecciones e inyecciones, y otra que usa números cardinales. La cardinalidad de un conjunto también se conoce como su tamaño, cuando no es posible confundir con otras nociones de tamaño. La cardinalidad de un conjunto A se denomina generalmente A, con una barra vertical en cada lado; Esta es la misma notación como valor absoluto y el significado depende del contexto. Alternativamente, la cardinalidad de un conjunto A puede estar denotada por n, A, tarjeta o # A.
definición de cardinality en el diccionario inglés
La definición de cardinalidad en el diccionario es propiedad de poseer un número cardinal. Otra definición de cardinalidad es el número cardinal asociado con la clase dada. Dos clases tienen la misma cardinalidad si se pueden poner en correspondencia uno-a-uno.
