Reply to Comment on 'Topological invariants, instantons, and the chiral anomaly on spaces with torsion
(2001-01-01)
We respond to the claim by Kreimer and Mielke to the effect that the Nieh-Yan topological invariant cannot contribute to the chiral anomaly in spaces with torsion.

Extended seminorms and extended topological vector spaces
(2016)
We introduce the notions of extended topological vector spaces and extended seminormed spaces, following the main ideas of extended normed spaces, which were introduced by G. Beer and J. Vanderwerff. We provide a topological ...
Topological signatures in CMB temperature anisotropy maps
(American Physical Soc, 2005-11-01)
We propose an alternative formalism to simulate cosmic microwave background (CMB) temperature maps in Lambda CDM universes with nontrivial spatial topologies. This formalism avoids the need to explicitly compute the ...

We propose an alternative formalism to simulate cosmic microwave background (CMB) temperature maps in ΛCDM universes with nontrivial spatial topologies. This formalism avoids the need to explicitly compute the eigenmodes ...
QUASI-TOPOLOGICAL QUANTUM FIELD THEORIES AND Z(2) LATTICE GAUGE THEORIES
(WORLD SCIENTIFIC PUBL CO PTE LTDSINGAPORE, 2012)
We consider a two-parameter family of Z(2) gauge theories on a lattice discretization T(M) of a three-manifold M and its relation to topological field theories. Familiar models such as the spin-gauge model are curves on a ...
Understanding topological insulators in real space
(MDPI, 2021)
A real space understanding of the Su-Schrieffer-Heeger model of polyacetylene is introduced thanks to delocalization indices defined within the quantum theory of atoms in molecules. This approach enables to go beyond the ...
Borel and Hausdorff hierarchies in topological spaces of Choquet games and their effectivization
(Cambridge University Press, 2015-10)
What parts of the classical descriptive set theory done in Polish spaces still hold for more general topological spaces, possibly T0 or T1, but not T2 (i.e. not Hausdorff)? This question has been addressed by Selivanov in ...
