Abstract
The -Hoggatt triangle is a lower triangular matrix whose entries are given by specific minors of Pascal's triangle formed by consecutive rows and columns. The cases correspond to Pascal's triangle, the Narayana triangle, and the Baxter triangle, respectively. In this paper, we present the infinite log-concavity of the row and column sequences, the log-concavity of the sequences along transversals, and the eventual log-convexity of the sequences along rays of the -Hoggatt triangle. In addition, we prove the asymptotic normality of the row sequences and total positivity of the -Hoggatt triangle.
