E. Celeghini et M. Rasetti, THE GAUSSIAN POLYNOMIAL, RESTRICTED K-ROWED PLANE PARTITIONS AND HOPF-ALGEBRAS, letters in mathematical physics, 40(2), 1997, pp. 171-176
Resorting to suitable representations of 9-algebras, we give a new pro
of of the theorem stating that the Gaussian polynomial defined by the
q-binomial coefficient is the weight (polynomial generating function)
of the restricted (i.e. limited in number and size of summands) k-rowe
d plane partitions.
