A study of symmetric points in Banach spaces
Debmalya Sain, Saikat Roy, Satya Bagchi +1
We completely characterize the left-symmetric points, the right-symmetric points, and, the symmetric points in the sense of Birkhoff-James, in a Banach space. We obtain a complete…
Extreme contractions on finite-dimensional polygonal Banach spaces-II
Anubhab Ray, Saikat Roy, Satya Bagchi +1
We introduce the concept of weak L-P property for a pair of Banach spaces, in the study of extreme contractions. We give examples of pairs of Banach spaces (not) satisfying weak L-…
Do non-free LCD codes over finite commutative Frobenius rings exist?
Sanjit Bhowmick, Alexandre Fotue-Tabue, Edgar Martínez-Moro +2
In this paper, we clarify some aspects on LCD codes in the literature. We first prove that a non-free LCD code does not exist over finite commutative Frobenius local rings. We then…
