We study the behavior of random walk in random environment (RWRE) on trees in the critical case left open in previous work. Representing the random walk by an electrical network, we assume that the ...

"A Random Walk Down Wall Street," written by Princeton economist Burton Malkiel, was first published in 1973. It became, at the time, an instant classic. The Random Walk idea postulated, in effect, ...

(Bloomberg) -- When Burton Malkiel published A Random Walk Down Wall Street 50 years ago, he said a blindfolded chimpanzee throwing darts could pick a stock portfolio that would do as well as one ...

WEST LAFAYETTE, Ind. — A new quantum random walk technique developed by engineers at Purdue University could eventually allow computers to search through data at speeds beyond that of conventional ...

The aim of this paper is to investigate discrete approximations of the exponential functional of Brownian motion (which plays an important role in Asian options of financial mathematics) with the help ...

For a random walk with drift, the best forecast of tomorrow's price is today's price plus a drift term. One could think of the drift as measuring a trend in the price (perhaps reflecting long-term ...

Purdue university researchers have developed a quantum computing technique that uses entangled photons, or qudits, instead of qubits. The key advantage of the technique is that it allows quantum ...
