Partition function zeros at first-order phase transitions: Pirogov-Sinai theory
Marek Biskup, Christian Borgs, Jennifer T. Chayes +1
This paper is a continuation of our previous analysis [BBCKK] of partition functions zeros in models with first-order phase transitions and periodic boundary conditions. Here it is…
Ultrarelativistic black hole in an external electromagnetic field and gravitational waves in the Melvin universe
Marcello Ortaggio
We investigate the ultrarelativistic boost of a Schwarzschild black hole immersed in an external electromagnetic field, described by an exact solution of the Einstein-Maxwell equat…
Ricci-corrected derivatives and invariant differential operators
David M. J. Calderbank, Tammo Diemer, Vladimir Soucek
We introduce the notion of Ricci-corrected differentiation in parabolic geometry, which is a modification of covariant differentiation with better transformation properties. This e…
Expected length of the longest common subsequence for large alphabets
Marcos Kiwi, Martin Loebl, Jiri Matousek
We consider the length L of the longest common subsequence of two randomly uniformly and independently chosen n character words over a k-ary alphabet. Subadditivity arguments yield…
Gravitational and electromagnetic fields near a de Sitter-like infinity
Pavel Krtous, Jiri Podolsky, Jiri Bicak
We present a characterization of general gravitational and electromagnetic fields near de Sitter-like conformal infinity which supplements the standard peeling behavior. This is ba…
On the least exponential growth admitting uncountably many closed permutation classes
Martin Klazar
We show that the least exponential growth of counting functions which admits uncountably many closed permutation classes lies between 2^n and (2.33529...)^n.
