Invert to Learn to Invert

open access: yesCoRR, 2019
Iterative learning to infer approaches have become popular solvers for inverse problems. However, their memory requirements during training grow linearly with model depth, limiting in practice model expressiveness. In this work, we propose an iterative inverse model with constant memory that relies on invertible networks to avoid storing intermediate ...

On the Tree Gauge in Magnetostatics

open access: yesJ, 2022
We recall the classical tree-cotree technique in magnetostatics. (1) We extend it in the frame of high-order finite elements in general domains. (2) We focus on its connection with the question of the invertibility of the final algebraic system arising ...

On solvability of elliptic boundary value problems via global invertibility [PDF]

open access: yesOpuscula Mathematica, 2020
In this work we apply global invertibility result in order to examine the solvability of elliptic equations with both Neumann and Dirichlet boundary conditions.

Model of General Split-BREAK Process

open access: yesRevstat Statistical Journal, 2015
This paper presents a modification (and partly a generalization) of STOPBREAK process, which is the stochastic model of time series with permanent, emphatic fluctuations.

Invertible classes

open access: yesTheoretical Computer Science, 2006
The paper studies the problem of invertibility of recursive operators which map \({\mathcal F}\) to \({\mathcal F}\), where \({\mathcal F}\) is a class of functions. Four increasingly stronger types of invertibility are introduced and it is shown that they are different.

Verifying Bit-vector Invertibility Conditions in Coq (Extended Abstract) [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
This work is a part of an ongoing effort to prove the correctness of invertibility conditions for the theory of fixed-width bit-vectors, which are used to solve quantified bit-vector formulas in the Satisfiability Modulo Theories (SMT) solver CVC4. While

GENERALIZED SHERMAN-MORRISON-WOODBURY FORMULA FOR THE G-DRAZIN INVERSE [PDF]

open access: yesJournal of Algebraic Systems
In this paper, we present generaized Sherman-Morrison-Woodbury formula for the g-Drazin inverse in a Banachalgebra. New results for the g-Drazin invertibility of amodified element a -cdb with the generalized Schur complementdd - badc are given.

On a Characterization of Finite-Dimensional Vector Spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2021
We provide a characterization of the finite dimensionality of vector spaces in terms of the right-sided invertibility of linear operators on them.
