Besides requiring special fonts and/or hyphenation patterns, typesetting of ancient languages, in particular classical Latin, requires that some stylistic points should be taken into consideration; for instance, medieval codices and Renaissance books should not be taken as models, but, if an old style flavor is desired, books printed in the late XVII century should be imitated. Particular atten...

In this paper we give efficient molecular computing solutions to seven well-known NP-complete problems, namely the Hamiltonian circuit, Path with forbidden pairs, Longest path, Monochromatic triangle, Partition into triangles, Partition into paths of length two, Circuit satisfiability problems in the Parallel filtering model of Amos et al.

One of the most difficult problems in classical relativity is to understand how and when singularities form. In the 1960’s, Hawking and Penrose proved that the existence of a closed trapped surface in an asymptotically flat spacelike hypersurface gives rise to a singularity in space-time. However, no proof based on pure partial differential equation arguments was found, and many questions remai...

We have studied the linear codes associated: a) with the surfaces V r−1 2 of order r − 1 of PG(r, q), analyzing in detail the case r = 4; b) with the Schubert subvarieties of the Grassmannian varieties.

This paper presents two unconventional links between quantum and classical physics. The first link appears in the study of quantum cryptography. In the presence of a spy, the quantum correlations shared by Alice and Bob are imperfect. One can either process the quantum information, recover perfect correlations and finally measure the quantum systems; or, one can perform the measurements first a...
