# How to create these Effects in photoshop? [closed]

Edit > Transform > Skew

In photoshop one can simply draw the box (=single layer) and add the texts.Insert the model as a layer, make it a little gray by reducing the contrast:

Create a new layer.

# How to create a folded/bent icon in Inkscape?

I am curious how to create this folded/bent icon in Inkscape?Fairly simple, like @joojaa said: Cut the image into 3 pieces and skew each.

# Text on a Path - Have Font Going from Big to Small [duplicate]

Tapered/sloped text effect in Illustrator (NOT skew or perspective)

Create path you want the text like.write text you want.

# Create a sort of parallelogram in illustrator

How can I create this sort of parallelogram in Illustrator?As others have sorta tried to say you can use the Shear tool (Skew is in Photoshop).

# is the set of skew-symmetric matrices with positive Pfaffians path connected?

Is the set of real $2n \times 2n$ skew-symmetric matrices having positive Pfaffians path connected?By definition, the Pfaffian is a polynomial in the entries $a_{ij}$ ($i<j$) such that $Pf(A)^2=\det A$, and $Pf(J_n)=1$, where
$$J_n=\begin{pmatrix} 0_n & I_n \\ -I_n & 0n \end{pmatrix}. # Euclidean Algorithm for differential operators The elements of such a ring are called skew polynomials or Ore polynomials.For Ore polynomials the usual polynomial addition holds. # Determining existence of p-adic point on a plane curve Is there an implemented algorithm that will take a polynomial f(x,y)\in\mathbb Z[x,y] and a prime p, and determine whether the equation f(x,y)=0 has a solution over \mathbb Q_p?My recollection is that Nils Bruin did this is in fair generality in Magma. # A palindromic polynomial and its derivative have the same number of zeros outside the unit circle. Reference? I am trying to find the original reference for a lemma attributed to Cohn (as in Schur-Cohn method): Let A(z) be a palindromic or skew-palindromic polynomial, and denote its derivative by A'(z).Then A(z) and A'(z) have the same number of zeros outside the unit circle. # Finding relations between invariant polynomials I already have the candidates for the generators (certain polynomials of 16 variables) but I need to find the relations between them.My question is the following - is it possible to force Magma, Sage or other program to find these polynomial relations (hopefully the whole ideal of relations. # The norm of a polynomial f in a skew polynomial ring must be in the center This is proved in Prop 1.7. # Algebraic integers in skew fields Hi everyone, let D be a skew field, which is finite dimensional over its center k.Assume that k is a number field, and let \mathcal{O}_D be the set of elements z\in D which are roots of a monic polynomial with coefficients in \mathcal{O}_k. # Global dimensions of non-commutative rings Moreover, are there any standard way to compute gl\dim(S) when S is non-commutative?Then let \sigma_1 be the k-algebra automorphism of R_1 defined by \sigma_1(x_1) = a_{21} x_1, and let R_2 be the skew-polynomial ring$$
R_2 = R_1[x_2; \sigma_1].

# (Non-)existence of skew fields satisfying a SGPI (=skew generalized polynomial identity)

From Kaplansky's PI-theorem it then follows that $K$ cannot satisfy a polynomial identity (the theorem says that primitive PI-algebras have finite dimension over their center).There, a GPI (generalized polynomial identity) has coefficients from the center $F$.

The pfaffian can be defined as $\sqrt{{\rm det}(A) }$ when $A$ is skew symmetric, or explicitly $${\rm pf}(A) = \frac{1}{2^n n!Let F \in k[x_0, \ldots, x_n ] be a homogeneous polynomial of degree d. # Skew polynomial algebra When I was a very little hare, a big grey wolf told me about the following skew polynomial algebra, which I never understood.My question is whether the following construction is a part of some bigger abstract construction and whether it is been written anywhere. # Map between skew polynomial ring and regular polynomial Let k be a field and q\in k -0.Define S_q := k\langle x, y\rangle/(xy - qyx), where k\langle x,y\rangle is the non-commutative polynomial ring. # Checking types in MAGMA In using MAGMA, I always get type errors.For example, I have made an empty set e := [], how would I make MAGMA print out the type of e? # Analogs of Cayley-Hamilton theorem for Pfaffian The Pfaffian \text{pf} is defined for a skew-symmetric matrix which is also a polynomial of matrix coefficients.One property for Pfaffian is that \operatorname {pf} (A)^{2}=\det(A) holds for every skew-symmetric matrix A. # Square root of the determinant of AB+I where A, B are skew-symmetric Imagine I have two skew-symmetric square matrices A, B.) Now I am interested in the square root of the determinant of AB+I, where I is the identity matrix,$$ x = \sqrt{ \det \left( AB + I \right) } $$As quick inspection for small matrices suggests that this x is a polynomial of the elements of A and B, for example for 3 \times 3 matrices we find$$ x = 1 - a_{12} b_{12} - a_{13} b_{13} - a_{23} b_{23} 

and I checked this analytically for matrices up to $6 \times 6$.

# Almost skew polynomial ring an integral domain?

Since Ore extensions of domains are Ore extensions, this question can be reformulated as follows: Since the relation look almost like those of a skew polynomial ring, can this ring in fact be written as a skew polynomial ring?Consider the $k$-algebra $R=k\langle x_i, c_i\rangle_{i=1,\ldots,n}$, $k$ not of characteristic 2,
subject to the following relations:

$x_ix_j = x_jx_i$ for all $i, j$
$x_ic_i = -c_i x_i$
$x_ic_j = c_j x_i$ for all $i\neq j$
$c_ic_j = -c_j c_i$ for all $i\neq j$

I haven't found a counterexample yet.
