Regular o no regular: el caso Airbnb en Perú

El regreso de las epidemias. Salud y sociedad en el Perú del siglo XX

extent the approaches to illness and healing have become "disenchanted" during this period or not. The authors have drawn on a broad range of archival sources, medical literature and field studies (as far as the more recent history is concerned). The studies in this volume show that Max Weber's concept of the "disenchantment of the world" may be perfectly applicable to many phenomena, but lack ...

Regular, pseudo-regular, and almost regular matrices

We give lower bounds on the largest singular value of arbitrary matrices, some of which are asymptotically tight for almost all matrices. To study when these bounds are exact, we introduce several combinatorial concepts. In particular, we introduce regular, pseudo-regular, and almost regular matrices. Nonnegative, symmetric, almost regular matrices were studied earlier by Ho¤man, Wolfe, and Ho¤...

Large regular graphs with no induced 2K2

Let r be a positive integer. Consider r-regular graphs in which no induced subgraph on four vertices is an independent pair of edges. The number v of vertices in such a graph does not exceed 5r/2; this proves a conjecture of Bermond. More generally, it is conjectured that if v > 2r, then the ratio v/r must be a rational number of the form 2 + 1/(2k). This is proved for v/r > 21 _ ~ . The extrem...

Regular Strongly Typical Blocks of O

We use the technique of Harish-Chandra bimodules to prove that regular strongly typical blocks of the category O for the queer Lie superalgebra qn are equivalent to the corresponding blocks of the category O for the Lie algebra gl n .
