Power Domains and Second-Order Predicates
Lower, upper, sandwich, mixed, and convex power domains are isomorphic to domains of second order predicates mapping predicates on the ground domain to logical values in a semiring. The various power domains diier in the nature of the underlying semiring logic and in logical constraints on the second order predicates.
متن کاملSyntactical Truth Predicates For Second Order Arithmetic
We introduce a notion of syntactical truth predicate (s.t.p.) for the second order arithmetic PA. An s.t.p. is a set T of closed formulas such that: i) T (t = u) iff the closed first order terms t and u are convertible, i.e. have the same value in the standard interpretation ii) T (A → B) iff (T (A) ⇒ T (B)) iii) T (∀xA) iff (T (A[x ← t]) for any closed first order term t) iv) T (∀XA) iff (T (A...
متن کاملRepresenting Powerdomain Elements as Monadic Second Order Predicates
This report characterizes the powerdomain constructions which have been used in the semantics of programming languages in terms of formulas of first order logic under a preordering of provable implication. This provides an intuitive representation which suggests a new form of powerdomain called the mixed powerdomain which expresses data in a different way from the well-known constructions from ...
متن کاملSecond Order General Slow-roll Power Spectrum
Recent combined results from theWilkinson Microwave Anisotropy Probe (WMAP) and Sloan Digital Sky Survey (SDSS) provide a remarkable set of data which requires more accurate and general investigation. Here we derive formulae for the power spectrum P(k) of the density perturbations produced during inflation in the general slowroll approximation with second order corrections. Also, using the resu...
متن کاملOn Second-Order Differential Power Analysis
Differential Power Analysis (DPA) is a powerful cryptanalytic technique aiming at extracting secret data from a cryptographic device by collecting power consumption traces and averaging over a series of acquisitions. In order to prevent the leakage, hardware designers and software programmers make use of masking techniques (a.k.a. data whitening methods). However, the resulting implementations ...
