Toward a Unified Light Curve Model for Multi-wavelength Observations of V1974 Cygni (nova Cygni 1992)
We present a unified model for optical, ultraviolet (UV), and X-ray light curves of V1974 Cygni (Nova Cygni 1992). Based on an optically thick wind model of nova outbursts, we have calculated light curves and searched for the best fit model that is consistent with optical, UV, and X-ray observations. Our best fit model is a white dwarf (WD) of mass 1.05 M⊙ with a chemical composition of X = 0.4...

This article demonstrates the invalidity of Theorem VI in Gödel’s monograph of 1931, by showing that (15) xBκ(17Gen r) −→ Bewκ[Sb(r Z(x))], (16) xBκ(17Gen r) −→ Bewκ[Neg(Sb(r Z(x))], (derived by means of definition (8.1) Q(x, y) ≡ xBκ[Sb(y Z(y))] respectively from (3) R(x1, . . . , xn) −→ Bewκ[Sb(r u1...un Z(x1)...Z(xn) )], (4) R(x1, . . . , xn) −→ Bewκ[Neg(Sb(r u1...un Z(x1)...Z(xn) )], of The...
متن کاملObservations Concerning Multidimensional
Schwartz introduced the idea of an ultracomputer and reviewed various basic algorithms for such an ensemble of processors containing ‘‘shuffle’’ interconnections. Later, Harrison and Kalos introduced the idea of an N-dimensional ultracomputer (N-D UC), which is well suited for implementing many algorithms. The main result of this note is that an N-D UC can simulate the right/left and shuffle/un...
متن کاملObservations concerning Gödel’s 1931
This article demonstrates the invalidity of Theorem VI in Gödel’s 1931, showing that propositions (15) and (16), derived from the definition 8.1, in its proof, are false in PA. Introduction. Developed as a consequence of the crisis of the foundation of mathematics due to the discovery of the antinomies, Hilbert’s formalism planned as criterions of adequacy for the axiomatic systems, the achieve...

This article demonstrates the invalidity of the so-called Gödel’s first incompleteness theorem, showing that propositions (15) and (16), derived from the definition 8.1 in Gödel’s 1931 article, are false. Introduction. Developed as a consequence of the crisis of the foundation of mathematics due to the discovery of the antinomies, Hilbert’s formalism planned as criterions of adequacy for the ax...
