Advances in Theoretical and Mathematical Physics, 2001 We establish a correspondence between toroidal compactifications of M-theory and del Pezzo surfaces. M-theory on T^k corresponds to P^2 blown up at k generic points; Type IIB corresponds to P^1\times P^1. The moduli of compactifications of M-theory on rectangular tori are mapped to Kahler moduli of del Pezzo surfaces.The U-duality group of M-theory ...

An Equivalent Linear Programming Form of General Linear Fractional Programming: A Duality Approach
Mathematics, 2021 Linear fractional programming has been an important planning tool for the past four decades. The main contribution of this study is to show, under some assumptions, for a linear programming problem, that there are two different dual problems (one linear ...

Synthese, 2019 AbstractWe advocate an account of dualities between physical theories: the basic idea is that dual theories are isomorphic representations of a common core. We defend and illustrate this account, which we call a Schema, in relation to symmetries. Overall, the account meshes well with standard treatments of symmetries.

Matrix Dimensional Analysis for Electromagnetic Quantities [PDF]
International Journal of Mathematical, Engineering and Management Sciences, 2021 We utilize the electromagnetically-oriented LTI∅ dimensional basis in the matrix solution of dimensional-analysis (DA) problems involving mainly electromagnetic quantities, whether these quantities are lumped or distributed.

Studia Rossica Posnaniensia, 2021 The hallmarks of space in Tsvetaeva’s poetic world are vertical orientation, two-worldness (many-worldness), measurability, and “immensity”, often expressed by asymmetry.

Journal of Anomalous Experience and Cognition, 2022 Objective. In the research presented here, quantum measurement is conceptualized as pragmatic information transfer when an intentional observer perceives motive-relevant quantum-based outcomes. Owing to the nature of pragmatic information as described in
