Measure Theoretic Entropy of Discrete Geodesic Flow on Nagao Lattice Quotient
1Department of Mathematical Education, Catholic Kwandong University, Gangneung 25601, Korea.
Abstract:
The discrete geodesic flow on Nagao lattice quotient of the space of bi-infinite geodesics in regular trees can be viewed as the right diagonal action on the double quotient of PGL2Fq((t-1)) by PGL2Fq[t] and PGL2(Fq[[t-1]]). We investigate the measure-theoretic entropy of the discrete geodesic flow with respect to invariant probability measures.

Entropy
When an ideal gas expands isothermally, the disorder in the gas increases. From the molecular perspective, the gas molecules have more volume to move around in.
Consider an infinitesimal step in the expansion, which...
Entropy and the Second Law of Thermodynamics
The relation between entropy and disorder can be illustrated with the example of the phase change of ice to water. In ice, the molecules are located at specific sites giving a solid state, whereas, in a liquid form, these molecules are much freer to move. The molecular arrangement has therefore become more randomized. Although the change in average...
Entropy Change in Reversible Processes
The statement can be further generalized to prove that entropy is a state function. Take a cyclic process between any two points on a p-V diagram.
