We consider the stochastic heat equation $$\partial _{s}u =\frac{1}{2}\Delta u +(\beta V(s,y)-\lambda )u$$ ? s = 1 2 ? + ( ? V , y ) - ? with a smooth space-time-stationary Gaussian random field V(s, y), in dimensions $$d\ge 3$$ d ? 3 an initial condition $$u(0,x)=u_0(\varepsilon x)$$ 0 x ? and suitably chosen $$\lambda \in {\mathbb {R}}$$ ? R . It is known that, for $$\beta $$ small enough, di...
This work is devoted to studying non-variational, nonlinear singularly perturbed elliptic models enjoying a double degeneracy character with prescribed boundary value in domain. In its simplest form, for each $\varepsilon>0$ fixed, we seek non-negative function $u^{\varepsilon}$ satisfying $$ \begin{cases} \left\[|\nabla u^{\varepsilon}|^p + \mathfrak{a}(x)|\nabla u^{\varepsilon}|^q \right] \De...
A triangle $T'$ is $\varepsilon$-similar to another $T$ if their angles pairwise differ by at most $\varepsilon$. Given a $T$, $\varepsilon>0$ and $n\in\mathbb{N}$, B\'ar\'any F\"uredi asked determine the maximum number of triangles $h(n,T,\varepsilon)$ being in planar point set size $n$. We show that for almost all there exists $\varepsilon=\varepsilon(T)>0$ such $h(n,T,\varepsilon)=n^3/24 (1+...
in this paper, we prove some results on characterization of $varepsilon$-simultaneous approximations of downward sets in vector lattice banach spaces. also, we give some results about simultaneous approximations of normal sets.

We investigate a degenerating elliptic problem in multi-structure $\Omega\_\varepsilon$ of $\mathbb{R}^3$, the framework thermal stationary conduction with highly contrasting diffusivity. Precisely, consists fixed basis $\Omega^-$ surmounted by thin cylinder $\Omega\_\varepsilon^+$ height $1$ and cross-section small diameter order $\varepsilon$. Moreover, $\Omega^+\varepsilon$ contains cylindri...
We study the existence, uniqueness and minimality of critical points form $m_{\varepsilon,\eta}(x) = (f_{\varepsilon,\eta}(|x|)\frac{x}{|x|}, g_{\varepsilon,\eta}(|x|))$ functional \[ E_{\varepsilon,\eta}[m] \int_{B^N} \Big[\frac{1}{2} |\nabla m|^2 + \frac{1}{2\varepsilon^2} (1 - |m|^2)^2 \frac{1}{2\eta^2} m_{N+1}^2\Big]\,dx \] for $m=(m_1, \dots, m_N, m_{N+1}) \in H^1(B^N,\mathbb{R}^{N+1})$ wi...
In this paper, we establish the discreteness of transmission eigenvalues for Maxwell's equations. More precisely, show that spectrum eigenvalue problem is discrete if electromagnetic parameters $\varepsilon, \, \mu, \hat \varepsilon, \mu$ in equations characterizing inhomogeneity and background are smooth some neighborhood boundary isotropic on boundary, satisfy conditions $\varepsilon \neq \va...
