Uniqueness of Walkup's 9-vertex 3-dimensional Klein bottle

Bhaskar Bagchi, Basudeb Datta

Via a computer search, Altshuler and Steinberg found that there are 1296 +1 combinatorial 3-manifolds on nine vertices, of which only one is non-sphere. This exceptional 3-manifold…

Minimal triangulations of sphere bundles over the circle

Bhaskar Bagchi, Basudeb Datta

For integers $d \geq 2$ and $ε = 0$ or 1, let $S^{1, d - 1} (ε)$ denote the sphere product $S^{1} \times S^{d - 1}$ if $ε = 0$ and the twisted $S^{d - 1}$ bundle over $S^{1}$ if $ε= 1…

On Nyman, Beurling and Baez-Duarte's Hilbert space reformulation of the Riemann hypothesis

Bhaskar Bagchi

There has been a surge of interest of late in an old result of Nyman and Beurling giving a Hilbert space formulation of the Riemann hypothesis. Many authors have contributed to thi…
