Due to their flexible makeup, they can provide stress relief in a pipe system. This is due to thermal and mechanical vibration or movement. Moreover, they provide a leak-proof protective barrier.
Further, spherical harmonics are basis functions for irreducible representations of SO (3), the group of rotations in three dimensions, and thus play a central role in the group theoretic discussion of SO (3). Spherical harmonics originate from solving Laplace's equation in the spherical domains. Zobraziť viac In mathematics and physical science, spherical harmonics are special functions defined on the surface of a sphere. They are often employed in solving partial differential equations in many scientific fields. Zobraziť viac Laplace's equation imposes that the Laplacian of a scalar field f is zero. (Here the scalar field is understood to be complex, i.e. to … Zobraziť viac The complex spherical harmonics $${\displaystyle Y_{\ell }^{m}}$$ give rise to the solid harmonics by extending from The Herglotz … Zobraziť viac The spherical harmonics have deep and consequential properties under the operations of spatial inversion (parity) and rotation. Zobraziť viac Spherical harmonics were first investigated in connection with the Newtonian potential of Newton's law of universal gravitation in three dimensions.

WebDavid Harrison. University of Toronto. A multipole expansion is a mathematical series representing a function that depends on angles—usually the two angles on a sphere. These series are useful because they can often be truncated, meaning that only the first few terms need to be retained for a good approximation to the original function.
