Study and suppression of singularities in wave-type evolution equations on non-convex domains with cracks
(Ankara Üniversitesi, 2022)One of the objectives of this paper is to establish the exact controllability for wave-type evolution equations on non-convex and/or cracked domains with non-concurrent support crack lines. Admittedly, we know that according ... -
A study on modeling of rat tumours with the discrete-time Gompertz model
(Ankara Üniversitesi, 2022)Cancer formation is one of the pathologies whose frequency has increased in the recent years. In the literature, the compartment models, which are non-linear, are used for such problems. In nonlinear compartment models, ... -
