Automorphism groups of non-normal affine toric surfaces

Kirill Selin

The paper studies automorphism groups of non‑normal affine toric surfaces and shows that, unlike the normal case, the connected component need not be generated by the acting torus…

Cluster structures on $S L_{n} / S O_{n}$

Jeff York Ye

The paper constructs cluster algebra structures on the strata of the symmetric space SL_n/SO_n by folding upper cluster algebras from SL_n, and shows these structures are compatibl…
