First principles calculations on theoretical band gap improvement of IIIA-VA zinc-blende semiconductor InAs
Waqas Mahmood, Arfan Bukhtiar, Muhammad Haroon +1
The structural, electronic, dielectric and vibrational properties of zinc-blende (ZB) InAs were studied within the framework of density functional theory (DFT) by employing local d…
Application of k . p method on band structure of GaAs obtained through joint density functional theory
Waqas Mahmood, Bing Dong
The structural and electronic properties of zinc-blende (ZB) GaAs were calculated within the framework of plane wave density-functional theory (DFT) code JDFTx by using Becke 86 in…
-Cohen Macaulay modules
Waqas Mahmood, Maria Azam
A finitely generated module over a commutative Noetherian ring is called an -Cohen Macaulay module, if \[ \grade(I,M) + \dim(M/IM)= \dim(M), \] where is a proper ide…
Roughness in quotient groups
Waqas Mahmood
The theory of rough sets was firstly introduced by Pawlak (see \cite{p}). Many Mathematician has been studied the relations between rough sets and algebraic systems such as groups,…
On generalized completion homology modules
Waqas Mahmood
Let be an ideal of a commutative Noetherian ring . Let and be any -modules. We define the generalized completion homology modules , for $i\in \mathb…
The Double Jones Birefringence in Magneto-electric Medium
Waqas Mahmood, Qing Zhao
In this paper, the Maxwell's equations for the tensorial magneto-electric (ME) medium have been solved which in fact is the extension of anisotropic nonmagnetic medium. All of the…
Cohomologically complete intersections with vanishing of Betti numbers
Waqas Mahmood
Let be ideal of an -dimensional local Gorenstein ring . In this paper we will describe several necessary and sufficient conditions such that the ideal becomes cohomol…
On natural homomorphisms of local cohomology modules
Waqas Mahmood
Let be a non-zero finitely generated module over a finite dimensional commutative Noetherian local ring with dim. Let be an ideal of with gr…
A Note on Endomorphisms of Local Cohomology Modules
Waqas Mahmood, Zohaib Zahid

On Cohomologically Complete Intersections in Cohen-Macaulay Rings
Waqas Mahmood
An ideal I of a local Cohen-Macaulay ring R is called a cohomologically complete intersection if H^i_I(R) = 0 for all i \neq c = height(I). Here H^i_I(R), i \in Z denotes the local…
A Few Comments On Matlis Duality
Waqas Mahmood
For a Noetherian local ring with $\mathfrak p\in \Spec(R)$ we denote by the -injective hull of . We will show that it has…
On Invariants and Endomorphism Rings of Local Cohomology Modules
Waqas Mahmood, Peter Schenzel
Let denote an -dimensional Gorenstein ring. For an ideal with $\grade I = c$ we define new numerical invariants as the socle dimens…
On Endomorphism Rings of Local Cohomology Modules
Waqas Mahmood
Let I be an ideal of a Complete Cohen-Macaulay local ring R of dimension n. We wil show that the natural homomorphism Rto HomR(HcI(KR), HcI(KR)) is an isomorphism provided that I i…
Experimental determination of heat capacities and their correlation with quantum predictions
Waqas Mahmood, Muhammad Sabieh Anwar, Wasif Zia
This article demonstrates an undergraduate experiment for the determination of specific heat capacities of various solids based on a calorimetric approach, where the solid vaporize…
