A Diffusion Equation with Exponential Nonlinearity Recant Developments
The purpose of this paper is to analyze in detail a special nonlinear partial differential equation (nPDE) of the second order which is important in physical, chemical and technical applications. The present nPDE describes nonlinear diffusion and is of interest in several parts of physics, chemistry and engineering problems alike. Since nature is not linear intrinsically the nonlinear case is t...
متن کاملNew Solutions for Fokker-Plank Equation of Special Stochastic Process via Lie Point Symmetries
In this paper Lie symmetry analysis is applied in order to find new solutions for Fokker Plank equation of Ornstein-Uhlenbeck process. This analysis classifies the solutions format of the Fokker Plank equation by using the Lie algebra of the symmetries of our considered stochastic process.
متن کاملWhy Are Symmetries a Universal Language of Physics? (on the unreasonable effectiveness of symmetries in physics)
In this paper, we prove that in some reasonable sense, every possible physical law can be reformulated in terms of symmetries. This result explains the wellknown success of group-theoretic approach in physics. 1 Formulation of the Problem Traditional physics used differential equations to describe physical laws. Modern physical theories (starting from quarks) are often formulated not in terms o...
متن کاملThe Symmetries of Equivalent Lagrangian Systems and Constants of Motion
In this paper Mathematical structure of time-dependent Lagrangian systems and their symmetries are extended and the explicit relation between constants of motion and infinitesimal symmetries of time-dependent Lagrangian systems are considered. Starting point is time-independent Lagrangian systems ,then we extend mathematical concepts of these systems such as equivalent lagrangian systems to th...
متن کاملDetecting Skewed Symmetries
Many surfaces of objects in our world are bounded by planar bilaterally symmetric gures. When these gures are imaged under orthographic projection a skewed symmetric contour results. In this paper a new fast, local method to recover skewed symmetries from curve segments is proposed. It can be applied to complete as well as to occluded contours. Furthermore, the skewed symmetry property is emplo...
متن کاملFractional superstrings with space-time critical dimensions four and six.
We propose possible new string theories based on local world-sheet symmetries corresponding to extensions of the Virasoro algebra by fractional spin currents. They have critical central charges c = 6(K + 8)/(K + 2) and Minkowski space-time dimensions D = 2+16/K for K ≥ 2 an integer. We present evidence for their existence by constructing modular invariant partition functions and the massless pa...
