p-adic Grothendieck Inequality, p-adic Johnson-Lindenstrauss Flattening and p-adic Bourgain-Tzafriri Restricted Invertibility Problems
K. Mahesh Krishna
We formulate p-adic versions of following three: (1) Grothendieck Inequality, (2) Johnson-Lindenstrauss Flattening Lemma, (3) Bourgain-Tzafriri Restricted Invertibility Theorem.
Functional Delsarte-Goethals-Seidel-Kabatianskii-Levenshtein-Pfender Bound
K. Mahesh Krishna
Pfender \textit{[J. Combin. Theory Ser. A, 2007]} provided a one-line proof for a variant of the Delsarte-Goethals-Seidel-Kabatianskii-Levenshtein upper bound for spherical codes,…
Noncommutative Equiangular Lines: van Lint-Seidel Relative and Gerzon Universal Bounds
K. Mahesh Krishna
We introduce the notion of noncommutative equiangular lines and derive noncommutative versions of fundamental van Lint-Seidel relative and Gerzon universal bounds.
p-adic Delsarte-Goethals-Seidel-Kabatianskii-Levenshtein-Pfender Bound
K. Mahesh Krishna
We introduce the notion of p-adic spherical codes (in particular, p-adic kissing number problem). We show that the one-line proof for a variant of the Delsarte-Goethals-Seidel-Kaba…
