Harmonic vs subharmonic
In mathematics, subharmonic and superharmonic functions are important classes of functions used extensively in partial differential equations, complex analysis and potential theory. Intuitively, subharmonic functions are related to convex functions of one variable as follows. If the graph of a convex function and a line intersect at two points, then the graph of the convex function is below the line between those points. In the same way, if the values of a subharmonic functio… Web2. is subharmonic. We say v ∈ C 2 ( U ¯) is subharmonic if − Δ v ≤ 0 in U ⊂ R n. Prove that v := D u 2 is subharmonic, whenever u is harmonic. This is Exercise 5, part d, in …

Websometimes referred to as a subharmonic of f 1. These definitions are summarized in Table 1. Table 1 – Harmonic and Interharmonic Definitions f 1 = fundamental frequency If n is any positive integer If m is any positive non-integer nf 1 is the n th harmonic mf 1 is the m th interharmonic If n = 0, nf 1 is DC If m < 1, mf 1 is a subharmonic WebDec 22, 2024 · Thus, the major difference between harmonics and sub-harmonics is that prior is having frequency of nf while latter have (1/n)f ,where f is fundamental frequency.
