A Novel Weak Fuzzy Solution for Fuzzy Linear System
Entropy, 2016 This article proposes a novel weak fuzzy solution for the fuzzy linear system. As a matter of fact, we define the right-hand side column of the fuzzy linear system as a piecewise fuzzy function to overcome the related shortcoming, which exists in the ...

Global weak solution for a periodic generalized Hunter–Saxton equation
Journal of Mathematical Analysis and Applications, 2012 In this paper, we consider a periodic generalized Hunter–Saxton equation. We obtain the existence of global weak solutions to the equation. First, we give the well-posedness result of the viscous approximate equations and establish the basic energy ...

Wavelet-Based Adaptive Solution for the Nonuniform Multiconductor Transmission Lines [PDF]
, 1998 —A time-domain technique for the solution of arbi-trary nonuniform multiconductor transmission lines (NMTL’s) is presented. The technique is based on a weak formulation of the NMTL equations obtained through spatial expansion of the voltage and current ...

One method to prove of existence weak solution of a mixed problem for 2D parabolic equations
Partial Differential Equations in Applied Mathematics, 2020 In this study using the residue method the solution of the first type mixed problem for 2D linear parabolic equation in the bounded cylinder of the Euclidean space R3(x,y,t)is obtained in explicit form. When the smoothness of initial data does not permit
