Math 139 Fourier Analysis Lecture 17: Fourier Inversion
Fourier Inversion: creating an approximation of the identity using dilated Gaussians; convolution of Schwartz class functions; uniform convergence to the original function of the convolution of the approximation of the identity with the function. Fourier inversion formula: multiplication

Abstract Algebra: Group actions are defined as a formal mechanism that describes symmetries of a set X. A given group action defines an equivalence relation, which in turn yields a partition of X into orbits. Orbits are also described as cosets of the group. U.Reddit course materials a

Poiseuille's Law - Pressure Difference, Volume Flow Rate, Fluid Power Physics Problems
This physics video tutorial provides a basic introduction into Poiseuille's law. It explains how to calculate the pressure difference required to maintain a constant volume flow rate using poiseuille's equation given the coefficient of viscosity, the cross-sectional radius and the length

EDIT: At 14:39, notation should be written pi_I:G maps to Bij(G/H). Then we can talk about Ker pi_I as a subgroup of G. Abstract Algebra: We consider the left regular action of G on the set X = G. We prove Cayley's Theorem, that every group is isomorphic to a subgroup of a symmetric g

GT16.1 Examples of Cayley's Theorem
Edit: Typo at 5:24. Second four cycles in pi(i) and pi(-i) should be (5768) and (5867), respectively. Abstract Algebra: We give further examples of Cayley's Theorem and its variant. Examples include the real numbers, the symmetry group of the square, and the quaternion group.
