Mathematics, 2022 We present a comprehensive study for common second order PDE’s in two dimensional disc-like systems and show how their solution can be approximated by finding the Green function of an effective one dimensional system.

Earthquake response of adjacent structures with viscoelastic and friction dampers [PDF]
Theoretical and Applied Mechanics, 2015 We study the seismic response of two adjacent structures connected with a dry friction damper. Each of them consists of a viscoelastic rod and a rigid block, which can slide without friction along the moving base.

Numerical solution of an intuitionistic fuzzy parabolic partial differential equation using an explicit cubic spline method [PDF]
Notes on IFSThis paper presents a numerical approach for solving intuitionistic fuzzy parabolic partial differential equations (IFPPDEs) using the explicit cubic spline method. Intuitionistic fuzzy systems, which extend classical fuzzy sets by incorporating a degree

An Optimal Control Problem by a Hyperbolic System with Boundary Delay
Известия Иркутского государственного университета: Серия "Математика", 2021 The paper deals with an optimal control problem by a system of semilinear hyperbolic equations with boundary differential conditions with delay. This problem is considered for smooth controls. Because this requirement it is impossible to prove optimality

Limit Cycles Bifurcating from Periodic Integral Manifold In Non-Smooth Differential Systems
Physica D: Nonlinear PhenomenaThis paper addresses the perturbation of higher-dimensional non-smooth autonomous differential systems characterized by two zones separated by a codimension-one manifold, with an integral manifold foliated by crossing periodic solutions. Our primary focus is on developing the Melnikov method to analyze the emergence of limit cycles originating from the
