Corrections

Abstract

The following corrections for “A Globally Gated Polling System with Server Interruptions, and Applications to the Repairman Problem” by O.J. Boxma, J.A. Weststrate, and U. Yechiali, which appeared in Volume 7, Number 2, of Probability in the Engineering and Informational Sciences, missed the press date.

p. 192, (3.3): X_i should be X_i

p. 194, (3.12):should be

p. 195, (4.1): N should be n in the five summations over n (15x)

p. 195, (4.2): should be moved to the next line (after the multiplication sign)

p. 195, below (4.3): Add: so that EY_1m = EX_m = λ_mEC

p. 195, (4.4): Add: for m < n

p. 195, I. –3: Add: for m < n

p. 196, (4.5): Add: for m < n

p. 196, I. 5: Add: Again cov(X_m, X_n) = λ_m λ_n var(C), independent of the server interruption process.
