Analytic integration of metric-valued functions in Lipschitz free spaces
Roger Arnau, Ãlvaro González Cortés, Enrique A. Sánchez Pérez
We develop an integration theory for functions taking values in a metric space. Following a Bochner-type construction, we define the concept of free integral as an element of the L…

Diagonalization of nonlinear functions in finite-dimensional spaces and the case of
Roger Arnau, Juan Carlos Cortés López, Ãlvaro González Cortés +1
This paper introduces a new theoretical framework for the diagonalization of nonlinear functions defined in finite-dimensional real Euclidean spaces. Extending classical results fr…

Galaxies at z > 10: ÎCDM predicts increased Star Formation Efficiency
Francisco Prada, Peter Behroozi, Tomoaki Ishiyama +4
We show that the rest-frame UV statistics and global properties of galaxies at 7 <= z <= 14 are naturally reproduced within the standard ÎCDM framework when galaxy formation is mo…
