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 ...

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 ...

Science often surprises us with its ability to connect seemingly unrelated phenomena. Have you ever stopped to marvel at how nature arranges itself into intricate patterns, like the spirals of a ...

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 ...
