WebbDetails about plethysm. I'm currently working on plethysm, i.e. the character of the composition S λ ( S μ ( V)) of the Schur functors S λ and S μ on a complex vector space V. We note this character s λ [ s μ]. One must know that the character of S μ ( V) is the Schur function s μ. We want to find the irreductible representation of S λ ... In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x. For example, since 1000 = 10 , the logarithm base 10 of 1000 is 3, or log10 (1000) = 3. The logarithm of x to base b is denoted as logb (x), or without parentheses, logb x, or even without the explicit base, log x, whe…

WebbSimplification and evaluation of logarithms is governed by several global flags: logexpand causes log(a^b)to become b*log(a). set to all, log(a*b)will also simplify to log(a)+log(b). If it is set to super, then log(a/b)will also simplify to (log(1/b), for binteger, always simplifies.) false, all of these simplifications will be turned off. logsimp quarter round wire channelWebb15 feb. 2024 · The rest of this article is arranged as follows: in Sect. 2, we introduce the basic notations for partitions, symmetric functions, and plethystic operators.Then, we … shipman canterbury talesWebb1 maj 2015 · The algebraic structure of the Coulomb branch of the 3d mirrors of A s, p models is captured by the plethystic logarithm of the Hilbert series of [10].
