Positive periodic solutions of singular systems of first order ordinary differential equations
Periodic solutions singular system Krasnoselskii fixed point
2010/12/10
The existence and multiplicity of positive periodic solutions for first non-autonomous singular systems are established with superlinearity or sublinearity assumptions atinfinity for an appropriately ...
Memory State Feedback Control for Singular Systems with Multiple Internal Incommensurate Constant Point Delays
Singular systems Multiple internal point delays Descriptor integral-inequality
2008/12/31
In this paper, the problem of delay-dependent stabilization for singular linear continuous-time systems with multiple internal incommensurate constant point delays (SLCS-MIID) is investigated. The con...

Canonical Treatment of Regular Lagrangians with Holonomic Constraints as Singular Systems
Regular Lagrangians Holonomic Constraints Singular Systems
2010/4/15
Regular Lagrangians with holomonic constraints are treated as singular systems using the canonical method. The Lagrange multipliers are introduced as generalized coordinates. The regular Lagrangians a...
