Splines in geometry and topology [PDF]
Computer Aided Geometric Design, 2016 This survey paper describes the role of splines in geometry and topology, emphasizing both similarities and differences from the classical treatment of splines. The exposition is non-technical and contains many examples, with references to more thorough treatments of the subject.

Lagrangian topology and enumerative geometry [PDF]
Geometry & Topology, 2012 We use the "pearl" machinery in our previous work to study certain enumerative invariants associated to monotone Lagrangian submanifolds.

Stochastic geometry and topology of non-Gaussian fields. [PDF]
Proc Natl Acad Sci U S A, 2012 Gaussian random fields pervade all areas of science. However, it is often the departures from Gaussianity that carry the crucial signature of the nonlinear mechanisms at the heart of diverse phenomena, ranging from structure formation in condensed matter

Smooth approximations and their applications to homotopy types
Pracì Mìžnarodnogo Geometričnogo Centru, 2020 Let $M, N$ the be smooth manifolds, $\mathcal{C}^{r}(M,N)$ the space of ${C}^{r}$ maps endowed with the corresponding weak Whitney topology, and $\mathcal{B} \subset \mathcal{C}^{r}(M,N)$ an open subset.

Nuclear Physics B, 2020 Perturbative string amplitudes are correctly derived from the string geometry theory, which is one of the candidates of a non-perturbative formulation of string theory. In order to derive non-perturbative effects rather easily, we formulate topological string geometry theory.

On the geometry and the topology of parametric curves [PDF]
Proceedings of the 45th International Symposium on Symbolic and Algebraic Computation, 2020 We consider the problem of computing the topology and describing the geometry of a parametric curve in R. We present an algorithm, PTOPO, that constructs an abstract graph that is isotopic to the curve in the embedding space. Our method exploits the benefits of the parametric representation and does not resort to implicitization.

ICrAData - Software for InterCriteria Analysis [PDF]
International Journal Bioautomation, 2018 In this paper, we consider the InterCriteria Analysis (ICrA), which is based on the index matrices and intuitionistic fuzzy sets. We demonstrate the application of ICrA using the software ICrAData.

Error-Correcting Codes on Projective Bundles over Deligne–Lusztig Varieties
Mathematics, 2023 The aim of this article is to give lower bounds on the parameters of algebraic geometric error-correcting codes constructed from projective bundles over Deligne–Lusztig surfaces.

Cyclopermutohedron: geometry and topology [PDF]
European Journal of Mathematics, 2016 The face poset of the permutohedron realizes the combinatorics of linearly ordered partitions of the set $[n]=\{1,...,n\}$. Similarly, the cyclopermutohedron is a virtual polytope that realizes the combinatorics of cyclically ordered partitions of the set $[n+1]$.
