Spherical quadrilaterals with three non-integer angles [PDF]
, 2015 We classify spherical quadrilaterals up to isometry in the case when one inner angle is a multiple of pi while the other three are not. This is equivalent to classification of Heun's equations with real parameters and one apparent singularity such that ...

Metrics with four conic singularities and spherical quadrilaterals [PDF]
, 2014 A spherical quadrilateral is a bordered surface homeomorphic to a closed disk, with four distinguished boundary points called corners, equipped with a Riemannian metric of constant curvature 1, except at the corners, and such that the boundary arcs ...

On quadrilaterals in the suborbital graphs of the normalizer [PDF]
Transactions on Combinatorics, 2020 n this paper, we investigate suborbital graphs formed by $N\big(\Gamma_0(N)\big)$-invariant equivalence relation induced on $\hat{\mathbb{Q}}$. Conditions for being an edge are obtained as a main tool, then necessary and sufficient conditions for ...

RoomSLAM: Simultaneous Localization and Mapping With Objects and Indoor Layout Structure
IEEE Access, 2020 This article presents RoomSLAM, a Simultaneous Localization and Mapping (SLAM) method for mobile robots in indoor environments where environments are modeled by points and quadrilaterals in 2D space. Points represent positions of semantic objects whereas

Spherical metrics with conical singularities on a 2-sphere: angle constraints [PDF]
, 2015 In this article, we give a criterion for the existence of a metric of curvature 1 on a 2-sphere with n conical singularities of prescribed angles 2πθ1,...,2πθn and non-coaxial holonomy.

Generation of hybrid grids over plane domains
Computer Assisted Methods in Engineering and Science, 2023 The paper presents an algorithm of coverage 2-D multiconnected domain by trianlges and quadrilaterals. The zone covered with quadrilaterals is structured, thus the zone covered with triangles is unstructured.
