Gil Kalai (en hebreo: גיל קלעי‎; Tel Aviv, 2 de octubre de 1955) es un matemático israelí. Es profesor de matemáticas en la Universidad Hebrea de Jerusalén, y profesor adjunto de matemáticas y ciencias de la computación en la Universidad de Yale,[1]​ y el redactor del Israel Journal of Mathematics.[2]​

Trayectoria

Recibió su Ph.D. de la Universidad Hebrea en 1983, bajo la supervisión de Micha Perles,[3]​ y se unió a la facultad de la Universidad Hebrea en 1985 después de una beca postdoctoral en el Instituto Tecnológico de Massachusetts.[2]​ Recibió el Premio Pólya en 1992, el premio de Erdős de la Sociedad Matemática de Israel en 1993, y el Premio Fulkerson en 1994.[1]​

Es conocido por encontrar variantes del algoritmo símplex en programación lineal que puede ser demostrado corre en tiempo subexponencial,[4]​ por demostrar que cada propiedad monotónica de grafos tiene una transición de fase aguda,[5]​ por solucionar el problema de Borsuk (conocido como conjetura de Borsuk) en el número de piezas necesarias para particionar sistemas convexos en subconjuntos de un diámetro más pequeño,[6]​ y por su trabajo sobre la conjetura de Hirsch en el diámetro de politopos convexos y en combinatoria poliédrica más generalmente.[7]​
