Partial Model Theory as Model Theory [PDF]
I show that the partial truth of a sentence in a partial structure is equivalent to the truth of that sentence in an expansion of a structure that corresponds naturally to the partial structure. Further, a mapping is a partial homomorphism/partial isomorphism between two partial structures if and only if it is a homomorphism/isomorphism between their ...

Effective-Field Theory for Model High-Tc Cuprates
Starting with a minimal model for the CuO2 planes with the on-site Hilbert space reduced to only three effective valence centers [CuO4]7−,6−,5− (nominally Cu1+,2+,3+) with different conventional spin and different orbital symmetry, we propose a unified ...

Dynamic theory of the nuclear collective model [PDF]
The rotation-vibration model and the hydrodynamic dipole-oscillation model are unified. A coupling between the dipole oscillations and the quadrupole vibrations is introduced in the adiabatic approximation. The dipole oscillations act as a "driving force"

Analytic theory of the eight-vertex model [PDF]
We observe that the exactly solved eight-vertex solid-on-solid model contains an hitherto unnoticed arbitrary field parameter, similar to the horizontal field in the six-vertex model.

Algebras of binary isolating formulas for theories of modular products of graphs
This article discusses the problems of constructing and classifying algebras generated by modular products of cycles. We demonstrate that algebras of binary isolating, used to analyze relationships between binary formulas of a theory, can be naturally ...

Teoria wielości rzeczywistości Leona Chwistka. Rys krytyczny [PDF]
The purpose of this paper is to offer a logico‑philosophical critical overview of the theory of multiple realities (TWR). The paper is divided into three sections.

Despite much recent progress in model building with D-branes, it has been problematic to find a completely convincing explanation of gauge coupling unification.

Algebras of Binary Isolating Formulas for Homomorphic Product Theories
Algebras of distributions of binary isolating and semi-isolating formulas are objects that are derived for a given theory, and they specify the relations between binary formulas of the theory.

Thirring Model as a Gauge Theory [PDF]
We give another reformulation of the Thirring model (with four-fermion interaction of the current-current type) as a gauge theory and identify it with a gauge-fixed version of the corresponding gauge theory according to the Batalin-Fradkin formalism ...
