Decomposition of Time-Ordered Products and Path-Ordered Exponentials [PDF]
, 1998 We present a decomposition formula for $U_n$, an integral of time-ordered products of operators, in terms of sums of products of the more primitive quantities $C_m$, which are the integrals of time-ordered commutators of the same operators. The resulting

Exponential integrators for stochastic Schrödinger equations [PDF]
Physical Review E, 2020 We present a class of exponential integrators to compute solutions of the stochastic Schr dinger equation arising from the modeling of open quantum systems. In order to be able to implement the methods within the same framework as the deterministic counterpart, we express the solution using the Kunita's representation.

Rational solutions of pairs of diagonal equations, one cubic and one quadratic [PDF]
, 2014 We obtain an essentially optimal estimate for the moment of order 32/3 of the exponential sum having argument $\alpha x^3+\beta x^2$. Subject to modest local solubility hypotheses, we thereby establish that pairs of diagonal Diophantine equations, one ...

The Seiberg-Witten prepotential and the Euler class of the reduced moduli space of instantons [PDF]
, 2001 The n-instanton contribution to the Seiberg-Witten prepotential of N=2 supersymmetric d=4 Yang Mills theory is represented as the integral of the exponential of an equivariantly exact form.

Adaptive Exponential Integrators for MCTDHF [PDF]
, 2020 We compare exponential-type integrators for the numerical time-propagation of the equations of motion arising in the multi-configuration time-dependent Hartree-Fock method for the approximation of the high-dimensional multi-particle Schr{ }dinger equation.

Exponential type convexity and some related inequalities
Journal of Inequalities and Applications, 2020 In this manuscript, we give and study the concept of exponential type convex functions and some of their algebraic properties. We prove two Hermite–Hadamard (H-H) type integral inequalities for the newly introduced class of functions. We also obtain some
