A note on the relationship between rational and trigonometric solutions of the WDVV equations [PDF]

open access: yes, 2007
Legendre transformations provide a natural symmetry on the space of solutions to the WDVV equations, and more specifically, between different Frobenius manifolds.

Modular frobenius manifolds and their invariant flows [PDF]

open access: yes, 2010
The space of Frobenius manifolds has a natural involutive symmetry on it: there exists a map I which sends a Frobenius manifold to another Frobenius manifold.

The Seiberg-Witten equations on 3-manifolds with boundary [PDF]

open access: yes, 1999
The Seiberg-Witten equations have proved to be quite powerful in studying smooth 4-manifolds since their landing in 1994. The corresponding Seiberg-Witten theory on closed 3-manifolds can either be obtained by a dimension reduction from the four ...

LARGE SOLUTIONS FOR YAMABE AND SIMILAR PROBLEMS ON DOMAINS IN RIEMANNIAN MANIFOLDS [PDF]

open access: yes, 2011
We present a unified approach to study large positive solutions (i.e., u(x) -> infinity as x -> partial derivative Omega) of the equation Delta u + hu - k psi(u) = -f in an arbitrary domain Omega.

Square-integrability of solutions of the Yamabe equation [PDF]

open access: yes, 2011
We show that solutions of the Yamabe equation on certain n- dimensional non-compact Riemannian manifolds which are bounded and Lp for p = 2n=(n-2) are also L2. This Lp-L2-implication provides explicit constants in the surgery-monotonicity formula for the

Continuity equations and ODE flows with non-smooth velocity [PDF]

open access: yes, 2014
In this paper we review many aspects of the well-posedness theory for the Cauchy problem for the continuity and transport equations and for the ordinary differential equation (ODE). In this framework, we deal with velocity fields that are not smooth, but

Non-constructive interval simulation of dynamic systems [PDF]

open access: yes, 2012
In this report, inspired by non-constructive simulation developed in the qual-itative reasoning eld, we present a non-constructive interval simulation algorithm forthe simulation of dynamic systems.

Computing one-dimensional global manifolds of Poincaré maps by continuation [PDF]

open access: yes, 2005
We present an algorithm to compute one-dimensional stable and unstable manifolds of saddle periodic orbits in a Poincaré section. The computation is set up as a boundary value problem by restricting the beginning and end points of orbit segments to the ...

Practical Computational Exploration of Chemical Reaction Space: Assessing the Chemical Stability of Active Pharmaceutical Ingredients Under Acidic Conditions

open access: yesAngewandte Chemie, EarlyView.
Metadynamics simulations drive automated reaction exploration of acid‐catalysed drug degradation, generating a network spanning 1720 species and 2471 elementary steps. QM‐based filtering reduces the network to eight candidate pathways for rigorous DFT refinement and microkinetic modelling.
