Carrollian and celestial spaces at infinity
Journal of High Energy Physics, 2022 We show that the geometry of the asymptotic infinities of Minkowski spacetime (in d + 1 dimensions) is captured by homogeneous spaces of the Poincaré group: the blow-ups of spatial (Spi) and timelike (Ti) infinities in the sense of Ashtekar-Hansen and a ...

The exocenter and type decomposition of a generalized pseudoeffect algebra [PDF]
, 2012 We extend to a generalized pseudoeffect algebra (GPEA) the notion of the exocenter of a generalized effect algebra (GEA) and show that elements of the exocenter are in one-to-one correspondence with direct decompositions of the GPEA; thus the exocenter ...

International Journal of Applied Mathematics and Computer Science, 2021 The paper proposes an algorithm for safeness verification of a Petri net-based specification of the control part of cyber-physical systems. The method involves a linear algebra technique and is based on the computation of the state machine cover of a ...

Spatio-temporal evaluation of ecosystem services in the São Paulo Macrometropolis, Brazil
Revista Brasileira de Ciências Ambientais, 2023 Urbanization is one of the key factors that drive changes in ecosystem services. Although various studies have analyzed relationships between land-cover change and ecosystem services degradation, few have explored the impacts in future scenarios in mega ...
