Ramsey-Theory and Forcing Extensions [PDF]
Proceedings of the American Mathematical Society, 1994 In every forcing extension of every model of set theory by a nontrivial (set) forcing there exist a graph Y and a cardinal μ \mu , such that every graph has an edge coloring with μ \mu . colors with no monochromatic induced copy of Y.

Extensions of Perron–Frobenius theory [PDF]
Positivity, 2012 The classical Perron-Frobenius theory asserts that for two matrices $A$ and $B$, if $0\leq B \leq A$ and $r(A)=r(B)$ with $A$ being irreducible, then $A=B$. This was recently extended in Bernik et al. (2012) to positive operators on $L_p( )$ with either $A$ or $B$ being irreducible and power compact. In this paper, we extend the results to irreducible

Discrete-to-Continuous Extensions: Lovász Extension and Morse Theory
Discrete & Computational Geometry, 2023 AbstractThis is the first of a series of papers that develop a systematic bridge between constructions in discrete mathematics and the corresponding continuous analogs. In this paper, we establish an equivalence between Forman’s discrete Morse theory on a simplicial complex and the continuous Morse theory (in the sense of any known non-smooth Morse ...

Reliability Evaluation of Water-Rich Loess Tunnel with Lining Crack Based on Extension Theory
Advance in Civil Engineering, 2019 Crack is the most prevalent disease of water-rich loess tunnels, which impacts the tunnel safety and reliability. The study aimed to investigate the multi-index of tunnel lining crack based on extension theory and reliability evaluation. A new evaluation

Theory and Applications of Active Constellation Extension
IEEE Access, 2021 Active constellation extension (ACE) was originally developed to reduce the peak-to-average-power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems with quadrature amplitude modulation (QAM).

An Extension of Renewal Theory [PDF]
Proceedings of the American Mathematical Society, 1952 Renewal theory can be and has been viewed in several different ways. One way is to reduce the problems to those concerning the addition of independent, non-negative random variables having a common distribution. Accordingly we introduce the random variables X1, X2, * * *, independent, non-negative, and all possessing the same distribution function F(x)

Chern–Simons extension of ESK theory [PDF]
General Relativity and Gravitation, 2021 The commonly-known Chern-Simons extension of Einstein gravitational theory is written in terms of a square-curvature term added to the linear-curvature Hilbert Lagrangian. In a recent paper, we constructed two Chern-Simons extensions according to whether they consisted of a square-curvature term added to the square-curvature Stelle Lagrangian or of one
