... the Anti-symmetric Analog? Howe and Umeda [H-U], and independently, Kostant and Sahi [K-S] discovered and proved an anti-symmetric analog of Capelli’s identity. Although we, at present, are unable ... to give a combinatorial proof similar to the above proofs, we state this identity in the hope that one of our readers will supply such a proof. Since the anti-symmetric analog is only...
