Pressure is the amount of force applied per unit area. Pressure can be measured by a pressure gauge, but it is important to know the type of pressure the gauge is reading. This article will cover the ...

Let S: X → X, T: Y → Y be continuous maps of compact metrizable spaces, and let π: X → Y be a continuous surjection with π ⚬ S = T ⚬ π. We investigate the notion of relative pressure, which was ...
