Three explicit examples of Lie 2-groupoids

M. Jotz, L. Mußmächer

This note constructs three explicit classes of Lie -groupoids arising from double Lie groupoids via the bar construction of Artin and Mazur, following a result of Mehta and Tang…

Hedlund-Metrics and the Stable Norm

Madeleine Jotz

The real homology of a compact Riemannian manifold is naturally endowed with the stable norm. The stable norm on arises from the Riemannian length functiona…

Closedness of the tangent spaces to the orbits of proper actions

Madeleine Jotz, Karl-Hermann Neeb

In this note we show that for any proper action of a Banach--Lie group on a Banach manifold , the corresponding tangent maps $\g \to T_x(M)$ have closed range for each $x \i…
