The Accessibility Capability Boundary: Operational Limits and Expansion Potential of AI-Generated Browser-Native Accessibility Systems
Rizwan Jahangir, Daisuke Ishii
As large language models (LLMs) demonstrate increasing competence in synthesizing functional user interfaces, a fundamental question emerges in accessibility computing: \textit{how…
Explainable PQC: A Layered Interpretive Framework for Post-Quantum Cryptographic Security Assumptions
Daisuke Ishii, Rizwan Jahangir
This paper studies how post-quantum cryptographic (PQC) security assumptions can be represented and communicated through a structured, layered framework that is useful for technica…
Canonical Lattices of Integer Relations Associated to Rational Fans: Wall Generation and a Two-Step Support Filtration
Rizwan Jahangir, Daisuke Ishii
We study the lattice of integer relations among the primitive ray generators of a rational fan , from an intrinsic, co…
Combinatorial Cycle Classes in the Intersection Cohomology of Projective Toric Varieties
Rizwan Jahangir, Daisuke Ishii
We investigate cycle-class realizations inside the combinatorial intersection cohomology for fans developed by Barthel, Brasselet, Fieseler, and Kaup (BBFK). For projective toric v…
Collections of cells, binomial ideals and combinatorics
Carmelo Cisto, Rizwan Jahangir, Francesco Navarra
In this paper we provide a description of the package \textit{PolyominoIdeals} for \textit{Macaulay2} that allows to deal with collections of cells, polyominoes and related binomia…
On Cohen-Macaulay non-prime collections of cells
Carmelo Cisto, Rizwan Jahangir, Francesco Navarra
In this paper we investigate Cohen-Macaulayness, Gorensteinness and the Hilbert-Poincaré series for some classes of non-prime collections of cells. In particular, we show that all…
Shellable simplicial complex and switching rook polynomial of frame polyominoes
Rizwan Jahangir, Francesco Navarra
Let be a frame polyomino, a new kind of non-simple polyomino. In this paper we study the -polynomial of in terms of the switching rook polynomial…
On Cohen-Macaulay posets of dimension two and permutation graphs
Rizwan Jahangir, Dharm Veer
We characterize Cohen-Macaulay posets of dimension two; they are precisely the shellable and strongly connected posets of dimension two. We also give a combinatorial description of…
