A Partial Order on Bipartite Graphs with n Vertices
Emil Daniel Schwab
The paper examines a partial order on bipartite graphs (X1, X2, E) with n vertices, X1UX2={1,2,...,n}. This partial order is a natural partial order of subobjects of an object in a…
A Note on the Stability of Exponential Dichotomy of Linear Differential Equations
Osvaldo Mendez, Nada al Hanna
We present an elementary Functional Analytic proof of the roughness of Exponential Dichotomy of Ordinary Differential Equations (with exponential growth) on an arbitrary Banach Spa…
Dynamically Generated Anomalous Magnetic Moment in Massless QED
Efrain J. Ferrer, Vivian de la Incera
In this paper we investigate the non-perturbative generation of an anomalous magnetic moment for massless fermions in the presence of an external magnetic field. In the context of…
Hyperbolic (1,2)-knots in S^3 with crosscap number two and tunnel number one
Luis G. Valdez-Sanchez, Enrique Ramirez-Losada
A knot in S^3 is said to have crosscap number two if it bounds a once-punctured Klein bottle but not a Moebius band. In this paper we give a method of constructing crosscap number…
Isoscaling and the high Temperature limit
C. O. Dorso, C. M. Hernández, J. A. López +1
This study shows that isoscaling, usually studied in nuclear reactions, is a phenomenon common to all cases of fair sampling. Exact expressions for the yield ratio and app…
Dynamically Induced Zeeman Effect in Massless QED
Efrain J. Ferrer, Vivian de la Incera
It is shown that in non-perturbative massless QED an anomalous magnetic moment is dynamically induced by an applied magnetic field. The induced magnetic moment produces a Zeeman sp…
