Shannon, R\'enyi, and cumulative residual entropies of the Wigner and Husimi distributions are examined in the ground and excited states of a harmonic oscillator. The entropies of …
Webb24 maj 2024 · The Shannon capacity of a graph is an important graph invariant in information theory that is extremely difficult to compute. The Lovász number, which is based on semidefinite programming relaxation, is a well-known upper bound for the Shannon capacity. During the late 1920s, Harry Nyquist and Ralph Hartley developed a handful of fundamental ideas related to the transmission of information, particularly in the context of the telegraph as a communications system. At the time, these concepts were powerful breakthroughs individually, but they were not part of a comprehensive theory. In the 1940s, Claude Shannon developed the concept of channel capacity, based in part on the ideas of Nyquist and Hartley, and then formula…
