We investigate the tail behaviour of the steady state distribution of a stochastic recursion that generalises Lindley’s recursion. This recursion arises in queuing systems with dependent interarrival and service times, and includes alternating service systems and carousel storage systems as special cases. We obtain precise tail asymptotics in three qualitatively different cases, and compare the...

We study the renormalization group flow equations for correlation functions of weakly coupled quantum field theories in AdS. Taking limit where external points approach conformal boundary, we obtain a conformally invariant functions. solve one- and two-point show that corrections to dimensions can be obtained as an integral over Mellin amplitude four-point function. also derive higher $n$-point...

It is a truism that conceptual understanding of a hypothesis is required for its empirical investigation. However, the concept of recursion as articulated in the context of linguistic analysis has been perennially confused. Nowhere has this been more evident than in attempts to critique and extend Hauseretal's. (2002) articulation. These authors put forward the hypothesis that what is uniquely ...

We present a formal derivation of program schemes that are usually called Backtracking programs and Branch-and-Bound programs. The derivation consists of a series of transformation steps, specifically algebraic manipulations, on the initial specification until the desired programs are obtained. The well-known notions of linear recursion and tail recursion are extended, for structures, to elemen...
