Abstract: Multi-winner voting is a way to select a subset of candidates, rather than just one, in a single election process. It is easy to carry out, and has become common, but its properties are not well understood. Because the voter must use a single ballot to indicate his or her preferences over all of the candidates, many nuances of preference are difficult or impossible to express. Many forms of ballot have been proposed for multi-winner voting; for some of them, there are multiple ways to determine the winning subset from a set of submitted ballots. Generally, these counting procedures balance two objectives - to elect only candidates who are well-supported individually, and to elect a subset of candidates with broad support. The breadth of multi-winner ballots and counting procedures is surveyed, and some properties that are desirable in multi-winner voting are described. La votación con múltiples ganadores es una forma de seleccionar un subconjunto de candidatos, en lugar de solo uno, en un solo proceso de elección. Es fácil de llevar a cabo y se ha vuelto de uso común, pero no se comprenden bien sus propiedades. Debido a que el votante debe usar una sola papeleta para indicar sus preferencias sobre todos los candidatos, muchos matices de preferencia son difíciles o imposibles de expresar. Se han propuesto muchas formas de votación para la votación de ganadores múltiples; para algunos de ellos, hay múltiples formas de determinar el subconjunto ganador de un conjunto de papeletas enviadas. En general, estos procedimientos de recuento equilibran dos objetivos: elegir candidatos que tengan un buen apoyo individual, y elegir un subconjunto de candidatos con amplio respaldo. Se estudia el alcance de los procedimientos de recuento y votación de ganadores múltiples y se describen algunas propiedades que son deseables en la votación con múltiples ganadores.
