New conditions for the existence of equilibrium prices [PDF]
Yugoslav Journal of Operations Research, 2018 We study the existence of equilibrium price vector in a supply-demand model taking into account the transaction costs associated with the sale of products.

Nonstabilized Nielsen coincidence invariants and Hopf--Ganea homomorphisms
, 2006 In classical fixed point and coincidence theory the notion of Nielsen numbers has proved to be extremely fruitful. We extend it to pairs (f_1,f_2) of maps between manifolds of arbitrary dimensions, using nonstabilized normal bordism theory as our main ...

Coincidence points of mappings in Banach spaces [PDF]
Fixed Point Theory, 2020 In this article we prove an existence theorem for coincidence points of mappings in Banach spaces. This theorem generalizes the Kantorovich fixed point theorem.

Coupled fixed points of (ϕˆ,ψˆ,θˆ)-contractive mappings in partially ordered b-metric spaces
Heliyon, 2022 We aim to prove the existence and uniqueness of the fixed points for the self mappings satisfying generalized contractions involving altering distance functions in ordered metric type space.

Maps on graphs can be deformed to be coincidence-free [PDF]
, 2010 We give a construction to remove coincidence points of continuous maps on graphs (1-complexes) by changing the maps by homotopies. When the codomain is not homeomorphic to the circle, we show that any pair of maps can be changed by homotopies to be ...

Coincidence of magnetic and valence quantum critical points in CeRhIn5 under pressure
, 2017 We present accurate electrical resistivity measurements along the two principle crystallographic axes of the pressure-induced heavy-fermion superconductor CeRhIn5 up to 5.63 GPa.

Coincident-point rigidity in normed planes
Ars Mathematica Contemporanea, 2023 A bar-joint framework $(G,p)$ is the combination of a graph $G$ and a map $p$ assigning positions, in some space, to the vertices of $G$. The framework is rigid if every edge-length-preserving continuous motion of the vertices arises from an isometry of the space.

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
Pediatric Blood &Cancer, EarlyView.ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

The dimensionless age of the Universe: a riddle for our time
, 2016 We present the interesting coincidence of cosmology and astrophysics that points toward a dimensionless age of the universe H_0*t_0 that is close to one.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
