Influence of Hysteresis on Magnetocaloric Performance at Cryogenic Temperatures: A Tb3Ni Case Study
Advanced Functional Materials, EarlyView.The existence of an inverse magnetocaloric effect in metamagnetic materials at cryogenic temperatures is investigated using multiple methods. Contrary to predictions from magnetization data, neither specific heat nor pulsed‐field measurements show such a cooling effect, instead indicating irreversible heating.

Uniqueness of a Polynomial and a Differential Monomial Sharing a Small Function
Annals of the West University of Timisoara: Mathematics and Computer Science, 2016 In this paper taking a question in [1] into background we investigate the uniqueness of a non-constant polynomial with the differential monomial generated by a non-constant mermorphic function f.

On the structure of isentropes of polynomial maps
, 2013 The structure of isentropes (i.e. level sets of constant topological entropy) including the monotonicity of entropy, has been studied for polynomial interval maps since the 1980s.

Irrationality of growth constants associated with polynomial recursions
, 2020 We consider integer sequences that satisfy a recursion of the form $x_{n+1} = P(x_n)$ for some polynomial $P$ of degree $d > 1$. If such a sequence tends to infinity, then it satisfies an asymptotic formula of the form $x_n \sim A α^{d^n}$, but little can be said about the constant $α$.

Schubert polynomial expansions revisited
Forum of Mathematics, SigmaWe give an elementary approach utilizing only the divided difference formalism for obtaining expansions of Schubert polynomials that are manifestly nonnegative, by studying solutions to the equation $\sum Y_i\partial _i=\operatorname {id}$ on ...

Approximating chromatic sum coloring of bipartite graphs in expected polynomial time
Труды Института системного программирования РАН, 2018 It is known that if P≠NP the sum coloring problem cannot be approximated within for some constant . We propose for arbitrary small an approximation scheme for this problem that works in expected polynomial time.
