Some Generalizations of Quasi-symmetric Functions and Noncommutative Symmetric Functions

2000
In this paper, we investigate various kinds of generalisations of symmetric functions. The classical algebra Sym of symmetric functions is embedded in QSym, the algebra of quasi-symmetric functions, and is also a quotient of the algebra Sym of noncommutative symmetric functions.

Generalized symmetric and generalized pseudo-symmetric functions

ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003
We introduce generalized symmetric and generalized pseudo-symmetric functions which can be represented as regular two-dimensional linear arrays. It is possible due in part to generalized symmetries, which can be used when functions are represented using exor-based decompositions. We also identify and use local symmetries.

Complex symmetric functions and generalized discrete Fourier transform

Rendiconti del Circolo Matematico di Palermo, 1996
Let \(\Omega^{[k]}\) be the class of holomorphic functions \(f(z)\) of the complex variable \(z\) which satisfy, with respect to the \(s\)th root of unity \(\varepsilon_k\), \(k=0,1,\dots,n-1\), the symmetry property \(f(\varepsilon_1z)=\varepsilon_kf(z)\).

Threshold Element-Based Symmetric Function Generators and Their Functional Extension

2002
This paper presents threshold element-based symmetric function generators (SFG) and techniques for their functional extension. Any symmetric function of k input variables is realized by SFGs with (k+ 1) configuration bits. When less than k input variables are applied to the SFGs, certain logic functions beyond symmetric functions can be achieved by ...

The Generating Function Method for Quadratic Asymptotically Symmetric Birth and Death Processes

SIAM Journal on Applied Mathematics, 1984
This paper is a sequel to the second author, ibid. 42, 1020-1046 (1982; Zbl 0495.60088). Here the authors continue their work on the systems of birth and death processes with forward Kolmogorov equations \[ \partial p_ n/\partial t=-(\lambda_ n+\mu_ n)p_ n(t)\lambda_{n-1}p_{n- 1}(t)+\mu_{n+1}P_{n+1}(t) \] where \(\lambda_ n=\alpha (n^ 2+bn+c)\) and ...

Generalized Rotation Symmetric and Dihedral Symmetric Boolean Functions − 9 Variable Boolean Functions with Nonlinearity 242

2007
Recently, 9-variable Boolean functions having nonlinearity 241, which is strictly greater than the bent concatenation bound of 240, have been discovered in the class of Rotation Symmetric Boolean Functions (RSBFs) by Kavut, Maitra and Yucel. In this paper, we present several 9-variable Boolean functions having nonlinearity of 242, which we obtain by ...
