Combinatorics of semi-toric degenerations of Schubert varieties in type C
Naoki Fujita, Yuta Nishiyama
An approach to Schubert calculus is to realize Schubert classes as concrete combinatorial objects such as Schubert polynomials. Using the polytope ring of the Gelfand-Tsetlin polyt…
On a conjecture on 2-reduced Schur functions and Schur's Q-functions
Yuta Nishiyama
Motivated by Sato and Mori's work on the Korteweg-de Vries (KdV) equation and the modified KdV equation, Mizukawa, Nakajima, and Yamada made a conjecture on 2-reduced Schur functio…
Revisiting Unit Fractions That Sum To 1
Yutaka Nishiyama
This paper is a continuation of a previous paper. Here, as there, we examine the problem of finding the maximum number of terms in a partial sequence of distinct unit fractions lar…
Extending Sicherman Dice to 100-cell Calculation Tables
Yutaka Nishiyama, Nozomi Miyanaga
This paper discusses a 100-cell calculation table for addition, C(i,j)=Ai+Bj,(1<=i,j<=10), addressing the special case where the 100 cells C(i,j) comprise continuous numbers 0 thro…
A Sepak Takraw - Based Molecular Model For C60 - A Mathematical Study Of A 60-Atom Molecule
Yutaka Nishiyama
We mathematically investigate four molecular models of buckminsterfullerene (C60) discussing the strengths and weaknesses of each, and a new orthorhombic 20-dodecahedron model is p…
