primary-like and weakly primary-like submodules are two new generalizations of primary ideals from rings to modules. in fact, the class of primary-like submodules of a module lie between primary submodules and weakly primary-like submodules properly.  in this note, we show that these three classes coincide when their elements are submodules of a multiplication module and satisfy the primeful pr...

Weakly exchange-coupled biradicals have attracted much attention in terms of their DNP application in NMR spectroscopy for biological systems or the use of synthetic electron-spin qubits. Pulse-ESR based electron spin nutation (ESN) spectroscopy applied to biradicals is generally treated as transition moment spectroscopy from the theoretical side, illustrating that it is a powerful and facile t...

In the title compound, C11H14OS, all non-H atoms are essentially coplanar, with a mean deviation of 0.023 Å. In the crystal, centrosymmetrically related mol-ecules are weakly connected into dimers by pairs of C-H⋯O inter-actions. The dimers are further linked along the a axis by weak C-H⋯π and C-H⋯S inter-actions.

We prove that every surjective isometry from the unit sphere of space K(H), all compact operators on an arbitrary complex Hilbert H, onto real Banach Y can be extended to a linear K(H) Y. This is probably first example infinite dimensional non-commutative C*-algebra containing no unitaries and satisfying Mazur-Ulam property. also C*-algebras weakly JB*-triples satisfy

In this paper we prove existence the common fixed point with different conditions for $alpha-psi$-contractive mappings. And generalize weakly Zamfirescu map in to modified weakly Zamfirescu map.

The molecular structure of the title compound, C(21)H(26)N(2)O(2), shows two intra-molecular O-H⋯N hydrogen-bonding inter-actions. In the crystal structure, mol-ecular chains are formed along the c axis through weak C-H⋯O inter-actions. Neighbouring chains are weakly associated along the a axis via C-H⋯π inter-actions.

in this paper we prove existence the common fixed point with different conditions for $alpha-psi$-contractive mappings. and generalize weakly zamfirescu map in to modified weakly zamfirescu map.

banach contraction principle has been generalized in different spaces by mathematicians over the years. mustafa and sims [18] proposed a new class of generalized metric spaces, which are called as g-metric spaces. in this type of spaces a non-negative real number is assigned to every triplet of elements. many mathematicians studied extensively various results on g-metric spaces by using the con...

We show that the weakly over-penalized symmetric interior penalty (WOPSIP) method has high intrinsic parallelism. Consider the following model problem: Find u ∈ H 0 (Ω) such that a(u, v) = ∫ Ω fv dx ∀ v ∈ H 0 (Ω), where Ω ⊂ R is a bounded polygonal domain, f ∈ L2(Ω), and a(w, v) = ∫ Ω ∇w · ∇v dx. This problem can be solved by the weakly over-penalized symmetric interior penalty (WOPSIP) method ...
