Intrinsically harmonic forms and characterization of flat circle bundles

Elizeu França, Francesco Mercuri

We establish a criterion for the flatness of a principal circle bundle in terms of the intrinsically harmonic form problem. It states that the flatness is equivalent to the intrins…

Riemannian Hilbert manifolds

Leonardo Biliotti, Francesco Mercuri

In this article we collect results obtained by the authors jointly with other authors and we discuss old and new ideas. In particular we discuss singularities of the exponential ma…

The Gauss map of a complete minimal surface with finite total curvature

Luquesio P. Jorge, Francesco Mercuri

In [15] Robert Osserman proved that the image of the Gauss map of a complete, non flat minimal surface in R^3 with finite total curvature miss at most 3 points. In this paper we pr…

Minimal surfaces in 4-dimensional Lorentzian Damek-Ricci spaces

Adriana A. Cintra, Francesco Mercuri, Irene I. Onnis

In this paper we will construct a Weierstrass type representation for minimal surfaces in 4-dimensional Lorentzian Damek-Ricci spaces and we give some examples of such surfaces.

The Björling problem for minimal surfaces in a Lorentzian three-dimensional Lie group

Adriana A. Cintra, Francesco Mercuri, Irene I. Onnis

In this paper we will show the existence and uniqueness of the solution of the Björling problem for minimal surfaces in a 3-dimensional Lorentzian Lie group.

Properly discontinuous actions on Hilbert manifolds

Leonardo Biliotti, Mercuri Francesco

In this article we study properly discontinuous actions on Hilbert manifolds giving new examples of complete Hilbert manifolds with nonnegative, respectively nonpositive, sectional…
