Quadratic equations of tangent varieties via four-way tensors of linear forms
Junho Choe
In the present paper we construct quadratic equations and linear syzygies for tangent varieties using 4-way tensors of linear forms and generalize this method to higher secant vari…

A Fröberg type theorem for higher secant complexes
Junho Choe, Jaewoo Jung
We generalize the celebrated Fröberg's theorem to embedded joins of copies of a simplicial complex, namely higher secant complexes to the simplicial complex, in terms of property…
