... 05C30 Abstract There are many applications of the enumeration of maps in surfaces to other areas of mathematics and the physical sciences. In particular, in quantum field theory and string theory, there ... i 1  (i − 1) (p, q, n)-dipoles of the second type. In fact, even when considering different rootings of the same dipole, we can obtain different expressions for the...

... replacing the unknown distribution by the empirical distribution of the data in the definition of the statistical function, and then resampling the data to obtain a Monte Carlo distribution for the ... > 0), which completes the proof.  Proof of Theorem 2.1. If EX 2 < ∞ then s 2 n → σ 2 a.s. Therefore, the theorem follows if we show that the conditional d...
