Holomorphicity of Slice-Regular Functions [PDF]
Complex Analysis and Operator Theory, 2020 Slice-regular functions of a quaternionic variable have been studied extensively in the last 12 years, resulting, in many ways, quite close to classical holomorphic functions of a complex variable; indeed, there is a correspondence between slice-regular functions and a certain family of holomorphic maps from the complex plane to $\mathbb{C}^4$, as ...

Spherical Coefficients of Slice Regular Functions [PDF]
Results in Mathematics, 2021 AbstractGiven a quaternionic slice regular function f, we give a direct and effective way to compute the coefficients of its spherical expansion at any point. Such coefficients are obtained in terms of spherical and slice derivatives of the function itself. Afterwards, we compare the coefficients of f with those of its slice derivative $$\partial _{c}f$

$*$-exponential of slice-regular functions [PDF]
Proceedings of the American Mathematical Society, 2018 According to [5] we define the $*$-exponential of a slice-regular function, which can be seen as a generalization of the complex exponential to quaternions. Explicit formulas for $\exp_*(f)$ are provided, also in terms of suitable sine and cosine functions.

The complexity of central slice functions
Theoretical Computer Science, 1986 The k-slice of a Boolean function \(f(x_ 1,...,x_ n)\) is the function \(f_ k=(f\wedge T^ n_ k)\vee T^ n_{k+1}\), where \(T^ n_ k\) is the k-th threshold function. Berkowitz has shown that the nonmonotone combinational and monotone circuit complexities of any k-slice function differ by at most an additive term of O(n log\({}^ 2 n)\).

Accelerating global left-ventricular function assessment in mice using reduced slice acquisition and three-dimensional guide-point modelling [PDF]
Journal of Cardiovascular Magnetic Resonance, 2011 Background To investigate the utility of three-dimensional guide-point modeling (GPM) to reduce the time required for CMR evaluation of global cardiac function in mice, by reducing the number of image slices required for accurate quantification of left ...

Network Slice Robustness with Function Sets
NOMS 2024-2024 IEEE Network Operations and Management SymposiumNetwork slicing allows leveraging virtualization techniques for the creation of multiple, logically-isolated network instances over a shared infrastructure. In general, it is composed of a set of unique network functions with a specific physical capacity request.

A New Approach to Slice Analysis Via Slice Topology [PDF]
, 2021 In this paper we summarize some known facts on slice topology in the quaternionic case, and we deepen some of them by proving new results and discussing some examples. We then show, following Dou et al.
