Coexistence of an unstirred chemostat model with B-D functional response by fixed point index theory
Journal of Inequalities and Applications, 2016 This paper deals with an unstirred chemostat model with the Beddington-DeAngelis functional response. First, some prior estimates for positive solutions are proved by the maximum principle and the method of upper and lower solutions.

Third-order differential equations with three-point boundary conditions
Open Mathematics, 2021 In this paper, a third-order ordinary differential equation coupled to three-point boundary conditions is considered. The related Green’s function changes its sign on the square of definition. Despite this, we are able to deduce the existence of positive

Degrees of sensible lambda theories [PDF]
Journal of Symbolic Logic, 1978 SummaryA λ-theory T is a consistent set of equations between λ-terms closed under derivability. The degree of T is the degree of the set of Gödel numbers of its elements. is the λ-theory axiomatized by the set {M = N∣ M, N unsolvable}. A λ-theory is sensible iff T ⊃ ; for a motivation see [6] and [4].In §1 it is proved that the theory is Σ20-complete.

Conceptualizing degrees of theory of mind [PDF]
Proceedings of the National Academy of Sciences, 2018 Successful navigation of the social world requires making accurate inferences about the contents of other people’s minds, being able to represent in one’s own mind the thoughts, beliefs, and intentions of another. This “theory of mind” (ToM) ability allows us to explain and predict others’ behavior in terms of their mental states (1).

A Fredholm alternative for quasilinear elliptic equations with right-hand side measure
Advances in Nonlinear Analysis, 2016 We consider a quasilinear elliptic equation with right-hand side measure, which does not satisfy the usual coercivity assumption. We prove an existence result in the line of the Fredholm alternative. For this purpose we develop a variant of degree theory

Reducing the maximum degree of a graph: comparisons of bounds
Theory and Applications of Graphs, 2021 Let $\lambda(G)$ be the smallest number of vertices that can be removed from a non-empty graph $G$ so that the resulting graph has a smaller maximum degree.
