The convergence rates of the sums of α-mixing (or strongly mixing) triangular arrays of heterogeneous random variables are derived. We pay particular attention to the case where central limit theorems ...

Figure 2: Scanning SQUID micrograph of the flux state in a section of a triangular lattice (T = 4.2 K). In the zigzag configuration, all the half-fluxons are generated in a singly connected ...

We consider a locally compact group G and a limiting measure μ of a commutative infinitesimal triangular system (c.i.t.s.) Δ of probability measures on G. We show, under some restrictions on G, μ or Δ ...
