On Sums of Practical Numbers and Polygonal Numbers

ducvktran/on-sums-of-practical-numbers-and-polygonal-numbers 20 Mar 2024

Practical numbers are positive integers $n$ such that every positive integer less than or equal to $n$ can be written as a sum of distinct positive divisors of $n$.

On decompositions for Fano schemes of intersections of two quadrics

pbelmans/decomposing-fano-schemes 19 Mar 2024

We propose conjectural semiorthogonal decompositions for Fano schemes of linear subspaces on intersections of two quadrics, in terms of symmetric powers of the associated hyperelliptic (resp.

Flexible control function approach under different types of dependent censoring

willemsilias/fmcc 18 Mar 2024

In this paper, we consider the problem of estimating the causal effect of an endogenous variable $Z$ on a survival time $T$ that can be subject to different types of dependent censoring.

A path-dependent PDE solver based on signature kernels

crispitagorico/sigppde 18 Mar 2024

Specifically, we solve an optimal recovery problem by approximating the solution of a PPDE with an element of minimal norm in the signature reproducing kernel Hilbert space (RKHS) constrained to satisfy the PPDE at a finite collection of collocation paths.

The Share-a-Ride Problem with mixed ride-hailing and logistic vehicles

shenglin807/sarp_rl_dataset 18 Mar 2024

An exact solution framework is proposed by (1) generating a feasible trip that serves a given set of requests at maximal profits; (2) generating all feasible trips for the entire set of passenger and parcel requests via an efficient enumeration method; and (3) finding all Pareto-optimal solutions of the bi-objective problem via an $\varepsilon$-constraint method.

An efficient algorithm for the Riemannian logarithm on the Stiefel manifold for a family of Riemannian metrics

smataigne/stiefellog.jl 18 Mar 2024

Since the popularization of the Stiefel manifold for numerical applications in 1998 in a seminal paper from Edelman et al., it has been exhibited to be a key to solve many problems from optimization, statistics and machine learning.
