Exercise 7.3 from Fundamentals of Galaxy Dynamics, Formation and Evolution by Ignacio Ferreras Neglect the pressure term in the linear growth of density uctu- ations
Exercise 7.3 from Fundamentals of Galaxy Dynamics, Formation and Evolution by Ignacio Ferreras Neglect the pressure term in the linear growth of density uctu- ations (i.e., the term with V28), and consider an empty Universe (i.e., zero matter and energy density). This is the Milne model. Show that in this case, density uctuations will remain constant with time
