What is the definition of two meromorphic functions sharing a small function? | Two meromorphic functions $f(z)$ and $g(z)$ sharing a small function
$\alpha(z)$ usually is defined in terms of vanishing of the functions
$f-\alpha$ and $g-\alpha$. We argue that it would be better to modify this
definition at the points where $\alpha$ has poles. Related to this issue we

Profile of a coherent vortex in two-dimensional turbulence at static pumping | We examine the velocity profile of coherent vortices appearing as a

Generic partiality for $\frac{3}{2}$-institutions | $\frac{3}{2}$-institutions have been introduced as an extension of

Independently Controllable Factors | It has been postulated that a good representation is one that disentangles

Determination and biological application of a time dependent thermal parameter and sensitivity analysis for a conduction problem with superficial evaporation | A boundary value problem, which could represent a transcendent temperature

Setting Boundaries with Memory: Generation of Topological Boundary States in Floquet-Induced Synthetic Crystals | When a d-dimensional quantum system is subjected to a periodic drive, it may

Latent Room-Temperature T$_c$ in Cuprate Superconductors | The ancient phrase, "All roads lead to Rome" applies to Chemistry and
