In mathematics, Hodge theory, named after W. V. D. Hodge, is a method for studying the cohomology groups of a smooth manifold M using partial differential equations.The key observation is that, given a Riemannian metric on M, every cohomology class has a canonical representative, a differential form that vanishes under the Laplacian operator of the metric.
Timpani produce inharmonic overtones, but are constructed and tuned to produce near-harmonic overtones to an implied missing fundamental. Hit in the usual way (half to three-quarters the distance from the center to the rim), the fundamental note of a timpani is very weak in relation to its second through fifth "harmonic" overtones.

In mathematics and mathematical physics, potential theory is the study of harmonic functions.. The term "potential theory" was coined in 19th-century physics when it was realized that two fundamental forces of nature known at the time, namely gravity and the electrostatic force, could be modeled using functions called the gravitational potential and electrostatic potential, both of which ...
Florence Huntley (née, Chance; 1855 – February 1, 1912) was an American journalist, editor, humorist, and occult author of the long nineteenth century.Hailing from Ohio, she married the writer Stanley Huntley in 1879 and during this marriage, she worked with him on his Spoopendyke sketches.

The result of Mehler can also be linked to probability. For this, the variables should be rescaled as x → x/ √ 2, y → y/ √ 2, so as to change from the 'physicist's' Hermite polynomials H (.) (with weight function exp(− x 2)) to "probabilist's" Hermite polynomials He (.) (with weight function exp(− x 2 /2)).
2005, 4). More than 11,000,000 Hispanic children are currently between the ages of 5 and 17. In terms of education policies that impact Hispanics, several major trends stand out: Low enrollment of Hispanic children in early childhood programs and kindergarten. Hispanic students tend to be less likely to be enrolled in these kinds of programs
