We consider the Standard Model on a non-commutative space and expand the action in the non-commutativity parameter θ . No new particles are introduced, the structure group is SU(3)×SU(2)×U(1). We derive the leading order action. At zeroth order the action coincides with the ordinary Standard Model. At leading order in θ we find new vertices which are absent in the Standard Model on commutative ...

The height of a polynomial with integer coefficients is the largest coefficient in absolute value. Many papers have been written on the subject of bounding heights of cyclotomic polynomials. One result, due to H. Maier, gives a best possible upper bound of nψ(n) for almost all n, where ψ(n) is any function that approaches infinity as n → ∞. We will discuss the related problem of bounding the ma...
متن کامل$n$-cocoherent rings, $n$-cosemihereditary rings and $n$-V-rings
Let $R$ be a ring, and let $n, d$ be non-negative integers. A right $R$-module $M$ is called $(n, d)$-projective if $Ext^{d+1}_R(M, A)=0$ for every $n$-copresented right $R$-module $A$. $R$ is called right $n$-cocoherent if every $n$-copresented right $R$-module is $(n+1)$-coprese-nted, it is called a right co-$(n,d)$-ring if every right $R$-module is $(n, d)$-projective. $R$...
متن کاملCancer Immunity (20 January 2011) Vol. 11, p. 1
Due to the high homology between the LAGE-1 and NY-ESO-1 proteins, we hypothesized that an anti-NY-ESO-1 vaccine might elicit LAGE-1 immunity and hence may be effective in multiple myeloma (MM) patients with LAGE-1-positive/NY-ESO-1-negative tumors. Therefore, we set out to evaluate LAGE-1 and NY-ESO-1 mRNA and protein expression in MM patients in a bid to evaluate possible benefits of their ho...

The purpose of this talk is to review a few issues concerning noncommutativity arising from String Theory. In particular, it is shown how in Type IIB Theory, the annihilation of a D3 − D3 brane pair yields a D1−string. This object, in the presence of a large B−field and fermions, happens to be a complex noncommutative soliton endowed with superconductivity. INTRODUCTION Type IIB Superstring The...
