Alternating sums in hyperbolic Pascal triangles
László Németh; László Szalay;Abstract
A new generalization of Pascal's triangle, the so called hyperbolic Pascal triangles were introduced in \cite{BNSz}. The mathematical background goes back to the regular mosaics in the hyperbolic plane. The alternating sum of elements in the rows was given in the special case $\{4,5\}$ of the hyperbolic Pascal triangles. In this article, we determine the alternating sum generally in the hyperbolic Pascal triangle corresponding to $\{4,q\}$ with $q\ge5$.
