Boundedness of Dehn surgery slopes admitting hyperbolic -representations for two-bridge knots

Shunjiang Jiang, Ran Tao

We study Dehn fillings on two-bridge knots via non-abelian representations into whose meridian image is hyperbolic. For each fixed nontrivial two-bridg…

Tree-like graphings, wallings, and median graphings of equivalence relations

Ruiyuan Chen, Antoine Poulin, Ran Tao +1

We prove several results showing that every locally finite Borel graph whose large-scale geometry is "tree-like" induces a treeable equivalence relation. In particular, our hypothe…

A construction of minimal linear codes from partial difference sets

Ran Tao, Tao Feng, Weicong Li

In this paper, we study a class of linear codes defined by characteristic functions of certain subsets of a finite field. We derive a sufficient and necessary condition for such a…

Connected sums of knots do not admit purely cosmetic surgeries

Ran Tao

Two Dehn surgeries on a knot are called purely cosmetic if their surgered manifolds are homeomorphic as oriented manifolds. Gordon conjectured that non-trivial knots in do no…

An infinite family of -ovoids of

Tao Feng, Ran Tao

In this paper, we construct an infinite family of -ovoids of the generalized quadrangle , for and . Together with the exampl…

Cable knots do not admit cosmetic surgeries

Ran Tao

Two Dehn surgeries on a knot are called purely cosmetic if their surgered manifolds are homeomorphic as oriented manifolds. Gordon conjectured that non-trivial knots in do no…
