High Energy Physics - Phenomenology
This is the first in a series of papers, in which we compute the third-order
QCD corrections to top-antitop production near threshold in e+ e- collisions.
The present paper provides a detailed outline of the strategy of computation in
the f...

It is one of the main properties of uniformly hyperbolic dynamics that points
of two distinct trajectories cannot be uniformly close one to another. This
characteristics of hyperbolic dynamics is called expansivity. Hirsch, Pugh and

We prove a new symplectic analogue of Kashiwara's Equivalence from D-module
theory. As a consequence, we establish a structure theory for module categories
over deformation quantizations that mirrors, at a higher categorical level, the

Well-posedness for a system of quadratic derivative nonlinear
Schr\"odinger equations with low regularity periodic initial data

Mathematics
Analysis of PDEs
We consider the Cauchy problem of a system of quadratic derivative nonlinear
Schr\"odinger equations which was introduced by M. Colin and T. Colin (2004) as
a model of laser-plasma interaction. For the nonperiodic case, the author
proved th...

Let K be a field of characteristic zero and let Sm/K be the category of
smooth and separated schemes over K. For an ind-scheme X (and more
generally for any presheaf of sets on Sm/K), we define its Chow groups

Analysis of PDEs
The paper is concerned with the change of probability measures μ along
non-random probability measure valued trajectories νt, t∈[−1,1].
Typically solutions to non-linear PDEs, modeling spatial development as time
progresses, g...

The phenomenological model with three active and three light sterile
neutrinos is considered taking into account terrestrial experimental data,
which indicate anomalies at short distances beyond the minimally modified
Standard Model with th...
A note on injective envelopes and von Neumann algebras

The article exhibits certain relations between the injective envelope I(A) of
a C*-algebra A and the von Neumann algebra generated by a representation lambda
of A provided it is injective. More specifically we show that there exist
positive...

We provide an overview on how to use the measurable selection techniques to
derive the dynamic programming principle for a general stochastic optimal
control/stopping problem. By considering its martingale problem formulation on
the canonic...
