  • Interesting fact: The Sahara Desert is over twice as big as the second largest desert in the world, The Australian Desert. The Sahara is 3.5 million square miles compared to the 1.47 million square miles of the Australian. This is "true" in the generic sense of the Autralian Desert. There is no Australian Desert. It is divided into many different deserts. What would be true would be to say the Sahara is bigger than the desert space in Australia (which is A LOT not sure how much as a percentage of the total land mass of australia).
    • n sureness The state of being sure or certain; certainty.

A note on the Poisson boundary of lamplighter random walks
On the other hand, Eq.(8) assumes the monotoniicc decrease of the energy scale Ω that is surely not rigorously true during the original SDRG in the S = 1 RAHC, therefore Eq.(8) is surely not accurately true.

We conjecture that the set S (β (t) ) (having the property that for any ε > 0, S (β (t) ) + ε contains almost surely the eigenvalues of outputs of random quantum channels) can be made smaller and actually optimal, thus yielding as a byproduct that all the values Hmin(Φ) converge almost surely.

This definition is nice because it is quite intuitive, but is not very satisfactory because of the almost sure in this definition: this only defines L(t, x) for fixed t almost surely and almost everywhere in x.
