The Capacity of a Family of Sticky Channels
Mladen Kovačević
We determine the capacity of a family of -ary sticky-insertion channels. Fix and , and let be the unique positive solution of $λ^d = (q-1) (λ^{d-1} + \cdots…
An Isodiametric Theorem and Lattice Diameter-Perfect Codes in
Mladen Kovačević
The root lattice , equipped with its graph distance (equivalently, one half of the ambient metric), is isometric to with the asymmetric Manhattan metri…
Maximum Probability of Independence in Transitive Matroids
Mladen Kovačević
Let be a matroid on a finite ground set , and suppose that the automorphism group of acts transitively on . We show the following: if are sampled ind…
An Information-Theoretic Analog of the Twin Paradox
Mladen Kovačević, Iosif Pinelis, Marios Kountouris
We revisit the familiar scenario involving two parties in relative motion, in which Alice stays at rest while Bob goes on a journey at speed along an arbitrary trajectory and…
Evaluation of the Gilbert-Varshamov Bound using Multivariate Analytic Combinatorics
Goyal Keshav, Duc Tu Dao, Han Mao Kiah +1
Analytic combinatorics in several variables refers to a suite of tools that provide sharp asymptotic estimates for certain combinatorial quantities. In this paper, we apply these t…
Optimal Error-Detecting Codes for General Asymmetric Channels via Sperner Theory
Mladen Kovačević, Dejan Vukobratović
Several communication models that are of relevance in practice are asymmetric in the way they act on the transmitted "objects". Examples include channels in which the amplitudes of…
