theory is a base for all scientific disciplines. theorizing is an important branch in architecture too. there are a little reference that tries to define theory and show the differences between theory in architecture and theory in other disciplines. this article aimed to show the characteristics of architectural theory. at first we try to review different books and articles which are written on...

in this paper we give conditions for a tuple of commutative bounded linear operators which holds in the property of the hypercyclicity criterion. we characterize topological transitivity and semi-hereiditarily of a dynamical system given  by an n-tuple of operators acting on a separable infinite dimensional banach space .

and Applied Analysis 3 Example 2.3. Let X be a subset in Rn defined as follows: X : { x1, x2 | 0 < x2 < x2 1, 0 < x1 < 2 } ∪ { 0, 0 }. 2.2 Consider the point u 0, 0 . Since the tangent line of the curve x2 x2 1 at point u is the line x2 0. Then, for any x ∈ X \ {u}, there exists 0 < λ0 < 1 such that u λη x, u / ∈ X, ∀λ ∈ 0, λ0 . 2.3 Therefore, there exists no vector-valued function η x, u / 0 s...

laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. factors evaluated were lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 ds cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). the maximum germination in salinity stres...

An r-uniform hypergraph H is semi-algebraic of complexity t=(d,D,m) if the vertices correspond to points in Rd and edges are determined by sign-pattern m degree-D polynomials. Semi-algebraic hypergraphs bounded provide a general framework for studying geometrically defined hypergraphs. The much-studied Ramsey number Rrt(s,n) denotes smallest N such that every t on contains either clique size s ...

let $r$ be a ring and $m$ a right $r$-module with $s=end_r(m)$. a module $m$ is called semi-projective if for any epimorphism $f:mrightarrow n$, where $n$ is a submodule of $m$, and for any homomorphism $g: mrightarrow n$, there exists $h:mrightarrow m$ such that $fh=g$. in this paper, we study sgq-projective and$pi$-semi-projective modules as two generalizations of semi-projective modules. a m...
