Optimal Exponent for Coalescence of Finite Geodesics in Exponential Last Passage Percolation
Lingfu Zhang
In this note, we study the model of directed last passage percolation on , with i.i.d. exponential weight. We consider the maximum paths from vertices $\left(0,\lfloo…

Temporal Correlation in Last Passage Percolation with Flat Initial Condition via Brownian Comparison
Riddhipratim Basu, Shirshendu Ganguly, Lingfu Zhang
We consider directed last passage percolation on with exponential passage times on the vertices. A topic of great interest is the coupling structure of the weights o…
