Unpacking Smart Contracts in the Legal Services: a systematic literature review
This paper employs a systematic literature review to construct a theoretical framework for the design of smart contracts in the field of legal services. The analysis of 32 studies is categorized into two types: descriptive and thematic. The descriptive analysis reveals that smart contracts serve as the foundation of current knowledge in this domain. Subsequently, a cyclical conceptual model is developed, illustrating the evolutionary progression of legal smart contracts and their interplay with preceding actions. Furthermore, the thematic analysis critically examines the literature, identifying challenges and concerns related to legal service offerings. The proposed model is then briefly applied to address these issues
Parameterized Uniform Complexity in Numerics: from Smooth to Analytic, from NP-hard to Polytime
The synthesis of classical Computational Complexity Theory with Recursive
Analysis provides a quantitative foundation to reliable numerics. Here the
operators of maximization, integration, and solving ordinary differential
equations are known to map (even high-order differentiable) polynomial-time
computable functions to instances which are `hard' for classical complexity
classes NP, #P, and CH; but, restricted to analytic functions, map
polynomial-time computable ones to polynomial-time computable ones --
non-uniformly!
We investigate the uniform parameterized complexity of the above operators in
the setting of Weihrauch's TTE and its second-order extension due to
Kawamura&Cook (2010). That is, we explore which (both continuous and discrete,
first and second order) information and parameters on some given f is
sufficient to obtain similar data on Max(f) and int(f); and within what running
time, in terms of these parameters and the guaranteed output precision 2^(-n).
It turns out that Gevrey's hierarchy of functions climbing from analytic to
smooth corresponds to the computational complexity of maximization growing from
polytime to NP-hard. Proof techniques involve mainly the Theory of (discrete)
Computation, Hard Analysis, and Information-Based Complexity
