Regularized Subjective-Surface Flow with Monotone Reaction: Viscosity Well-Posedness and Convergence
Markjoe O. Uba
We study the vanishing-regularization limit of the regularized subjective-surface model introduced for touching and dividing cell nuclei and previously analyzed for fixed positive…

Regularized Subjective-Surface Flow with Monotone Reaction: Global Classical Well-Posedness and Stability
Markjoe O. Uba
Touching and dividing cell nuclei may appear as connected structures in microscopy images, making it difficult to distinguish neighboring nuclei during segmentation. We introduce a…

Asymptotic limits of the principal spectrum point of a nonlocal dispersal cooperative system and application to a two-stage structured population model
Maria A. Onyido, Rachidi B. Salako, Markjoe O. Uba +1
This work examines the limits of the principal spectrum point, , of a nonlocal dispersal cooperative system with respect to the dispersal rates. In particular, we provide prec…
