Discrete cosine and sine transforms generalized to honeycomb lattice
Jiří Hrivnák, Lenka Motlochová
The discrete cosine and sine transforms are generalized to a triangular fragment of the honeycomb lattice. The honeycomb point sets are constructed by subtracting the root lattice…

Dual-root lattice discretization of Weyl orbit functions
Jiří Hrivnák, Lenka Motlochová
Four types of discrete transforms of Weyl orbit functions on the finite point sets are developed. The point sets are formed by intersections of the dual-root lattices with the fund…

On E-Discretization of Tori of Compact Simple Lie Groups: II
Jiří Hrivnák, Michal Juránek
Ten types of discrete Fourier transforms of Weyl orbit functions are developed. Generalizing one-dimensional cosine, sine and exponential, each type of the Weyl orbit function repr…
