Query: On the mean projection theorem for determinantal point processes   In this short note, we extend a mean projection theorem for discrete
determinantal point processes to the continuous case, thus strengthening a
known result in random linear algebra due to Ermakov and Zolotukhin. We also
give a new formula for the variance of the exterior power of the random
projection.
