A MAD Q-set

A MAD Q-set

A MAD (maximal almost disjoint) family is an infinite subset A of the infinite subsets of ω = {0, 1, 2, . . .} such that any two elements of A intersect in a finite set and every infinite subset of ω meets some element of A in an infinite set. A Q-set is an uncountable set of reals such that every subset is a relative Gδ set. It is shown that it is relatively consistent with ZFC that there exis...

Mad Cow and Variant Creutzfeldt-Jacob Disease: “Prions – Proteins which Set a Bad"

Recently, the “mad cow” scare has put diseases caused by prions on the front page. These diseases share a common link to a protein naturally produced by the cells of human beings as well as numerous vertebrate animals. PrP is a small protein – around a hundred times smaller than the smallest virus – and invisible to even the best electron microscope. The largest quantities of this protein are m...

بررسی اختلال معادلات ماتریسی x+a^*f(x)a=q

در این پایان نامه ابتدا شرایط وجود جواب برای معادلات ماتریسی و غیر خطی x+a^*f(x)a=q را بررسی نموده سپس به تحلیل اختلال در معادلات مذکور می پردازیم. در هر مبحث برای بیان و توضیح مطالب قضایا و مثال های عددی متعدد آورده شده است.
