On A Fixed Point Theorem For The Product Of Operators
, 2017 In this paper, we study the existence of fixed points for the product of nonlinear operators. This kind of fixed point theorems is necessary in consideration of quadratic differential and integral problems.

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1
FEBS Open Bio, EarlyView.The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

New Existence and Uniqueness Results for Fractional Differential Equations
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2013 In this paper, we study a class of boundary value problems of nonlinear fractional differential equations with integral boundary conditions. Some new existence and uniqueness results are obtained by using Banach fixed point theorem.

A nationwide student survey on biochemistry learning resources in Italy
FEBS Open Bio, EarlyView.We conducted a survey among Italian university students to investigate their preferred study materials for biochemistry. We then analyzed the collected data to identify these materials. This information may be valuable to the Biochemistry educational community. The graphical abstract was created with Claude (Opus 5.5; Anthropic, 2026).

Multiplicity of Solutions for a Class of Nonlinear Second-Order Robin Problems
四川大学学报. 自然科学版, 2017 In this paper,~we use the fixed point index theory to show the existence of multiple positive solutions for a class of second-order Robin problems $$ \left\{\begin{array}{ll} u''(t)-k^{2}u(t)+\lambda f(u(t))=0, ~~\ \ \ t\in (0,1),~~k\neq0,\\[2ex] u'(0)=0,

Well-Posedness of the Fixed Point Problem of Multifunctions of Metric Spaces
MathematicsWe consider a class of metrics which are equivalent to the Hausdorff metric in some sense to establish the well-posedness of fixed point problems associated with multifunctions of metric spaces, satisfying various generalized contraction conditions ...

Core Many-to-one Matchings by Fixed-point Methods [PDF]
We characterize the core many-to-one matchings as fixed points of a map. Our characterization gives an algorithm for finding core allocations; the algorithm is efficient and simple to implement.

Some generalizations of Kannan's fixed point theorem in K-metric spaces [PDF]
, 2012 We extend some known fixed point results for mappings satisfying Kannan type conditions to the context of K-metric spaces. Firstly, we prove a common fixed point result for noncommuting maps.

On Fixed Point and Almost Fixed Point Problems of Lower Semicontinuous Type Multivalued Mappings
Acta Mathematica Sinica, English Series, 2005 The authors obtain almost fixed point theorems and fixed point theorems for lower semicontinuous type multivalued mappings in metrizable H-spaces. As an application, they obtain a nonempty intersection theorem for a multivalued mapping on a compact H-convex space. The main results are good variants and generalizations of the almost fixed point theorems
