Hyperbolic equations are a class of partial differential equations (PDEs) characterized by properties that allow for the propagation of waves and signals at finite speeds, making them crucial in modeling dynamic systems such as acoustics, electromagnetism, and fluid dynamics. They are distinguished by having real and distinct eigenvalues, which leads to well-posed initial value problems and the ability to describe phenomena like shock waves and discontinuities.

Partial differential equations (PDEs) are equations that involve rates of change with respect to continuous variables and are fundamental in describing various physical phenomena such as heat, sound, fluid dynamics, and quantum mechanics. Solving PDEs often requires sophisticated analytical and numerical techniques due to their complexity and the variety of boundary and initial conditions they encompass.

Electromagnetism is a fundamental force in nature responsible for electric and magnetic phenomena, described by Maxwell's equations, which unify electricity, magnetism, and light as manifestations of the same force. It plays a crucial role in modern technology, from power generation and transmission to telecommunications and electronic devices.

Fluid dynamics is a branch of physics that studies the behavior of fluids (liquids and gases) in motion and the forces acting on them. It is essential for understanding natural phenomena and designing systems in engineering disciplines, including aerodynamics, hydrodynamics, and meteorology.

Shock waves are nonlinear propagating disturbances that occur when an object moves through a medium faster than the speed of sound in that medium, causing a sudden change in pressure, temperature, and density. They are characterized by an abrupt, nearly discontinuous change in the properties of the medium, often resulting in phenomena such as sonic booms or explosive waves.

shock waves

Discontinuities refer to points or intervals where a function is not continuous, meaning there is an abrupt change or gap in the function's value. These can occur in various forms, such as jump, infinite, or removable discontinuities, each affecting the behavior and analysis of mathematical functions differently.
