T-dualization of Gödel string cosmologies via Poisson–Lie T-duality approach
European Physical Journal C: Particles and Fields, 2021 Using the homogeneous Gödel spacetimes we find some new solutions for the field equations of bosonic string effective action up to first order in $$\alpha '$$ α ′ including both dilaton and axion fields.

Particles of Negative and Zero Energy in Black Holes and Cosmological Models
Universe, 2023 Particles with negative energies are considered for three different cases: inside the horizon of a Schwarzschild black hole, Milne’s coordinates in flat Minkowski space–time (Milne’s universe using nonsynchronous coordinates) and in the cosmological ...

Um desfile de escola de samba em homenagem a Gödel
REMATEC. Revista de Matemática, Ensino e Cultura, 2018 Neste artigo apresentamos a vida e a obra de Kurt Gödel (1906 – 1978) e o fizemos por meio da descrição e comentários de/sobre um fictício desfile de escola de samba homenageando-o bem como dos bastidores do desfile.

Homogeneous Gödel-type solutions in hybrid metric-Palatini gravity
European Physical Journal C: Particles and Fields, 2018 The hybrid metric-Palatini $$f({\mathscr {R}})$$ f(R) gravity is a recently devised approach to modified gravity in which it is added to the metric Ricci scalar R, in the Einstein–Hilbert Lagrangian, a function $$f({\mathscr {R}})$$ f(R) of Palatini ...

Gödel and Gödel-type universes in Brans–Dicke theory
Physics Letters B, 2016 In this paper, conditions for existence of Gödel and Gödel-type solutions in Brans–Dicke (BD) scalar–tensor theory and their main features are studied.

Incompletitud. Rebecca Goldstein. Incompleteness: The proof and paradox of Kurt Gödel
Educación Química, 2018 El teorema de Gödel es quizás el teorema más famoso de las matemáticas. Justamente, su fama deriva de su importancia, al haber modificado revolucionariamente el conocimiento existente y abrir rutas nuevas e insospechadas para su desarrollo posterior ...

European Physical Journal C: Particles and Fields, 2018 This paper contains a discussion of a relativistic spin-0 system in the presence of a Gödel-type background space-time. The Duffin–Kemmer–Petiau (DKP) equation in the presence of a Gödel-type background space-time is studied in detail. After a derivation

Wittgenstein´s Critique of Gödel´s Incompleteness Results [PDF]
, 2003 It is often said that Gödel´s famous theorem of 1931 is\ud equal to the Cretian Liar, who says that everything that he\ud says is a lie. But Gödel´s result is only similar to this\ud sophism and not equivalent to it.

Noûs, EarlyView.ABSTRACT It is a truism of mathematics that differences between isomorphic number systems are irrelevant to arithmetic. This truism is deeply rooted in the modern axiomatic method and underlies most strands of arithmetical structuralism, the view that arithmetic is about some abstract number structure.
