## Objects in 3D space: color contrast to the background

Is there a tool that allows me to choose the right colors for the following:

1. objects
2. background

in the 3D room. Colors should have the right contrast.

## TO UPDATE

An example of my background color options is:

Background Color: `#c8c8c8c` Object color: `#576675`

Background Color: `#888888` Object color: `#576675`

Background Color: `#444444` object color `#576675`

## oa.operator algebras – Compute norms of operator's polynomials in Hilbert space and generalize von Neumann inequality

To let $$T$$ to be an operator $$l ^ 2 ({ mathbb {Z} _ { geq 0}}) to l ^ 2 ({ mathbb {Z} _ { geq 0}})$$. $$e_n mapsto sqrt {1 – q ^ {2 (n + 1)}} e_ {n + 1}$$, Where $$0 , I would like to calculate $$| f (T, T ^ {*}) |$$ (Operator norm) for each $$f in mathbb {C} (z, bar z)$$, operator $$T ^ {*}$$Of course this is the Hilbert conjugate and $$T ^ {*} e_0 = 0$$. $$T ^ {*} e_n = sqrt {1-q ^ {2n}} e_ {n-1}$$ to the $$n> 0$$,

I am not sure if this calculation is possible at all, and I would like to show that $$| f (T, T ^ {*}) | to sup limits_ {| z | leq 1} f (z, bar z)$$ as $$q$$ goes to 1, because I actually have to calculate standards first.

I think that there is a generalization of von Neumann's inequality $$q$$analogue or so (there are many generalizations) because the usual inequality proves this for polynomials $$g in mathbb {C} (z)$$ (without $$bar z$$).

Question: Does anyone know of useful facts or inequalities related to my question? Something that could help.

## Can we write \$ sl (4, mathbb {C}) \$ as the vector space sum of two copies of \$ sl (3, mathbb {C}) \$?

We know $$sl (4, mathbb {C})$$ has dimension $$15$$ and $$sl (3, mathbb {C})$$ has dimension $$8$$, Is it possible to write $$sl (4, mathbb {C})$$ as the vector space sum of two Lie subalgebras that are isomorphic to $$sl (3, mathbb {C})$$?

## What is the dimension of the space of the Lie algebra homomorphisms between two Lie algebras of finite dimension?

Let g1 and g2 be two Lie algebras (finite dimensional). What is the linear space of homomorphisms of Lie algebra from g1 to g2?

## sg.symplectic geometry – Explanation of the "neck strain" applied to the basic space of a Lefschetz-Fibration

I ask this question because I want to better understand the argument of neck elongation in symplectic geometry and the possible conclusions in my environment.

Suppose I have a Lefschetz fibrillation $$E$$ about $$M$$, Where $$M$$ is an exact symplectic manifold (possibly with ends). To let $$C$$ be a contact type codimension $$1$$ Subtype of $$M$$, As far as I understand, when I stretch my neck $$C$$ I create a family of manifolds $$M_t$$. $$t in Bbb R ^ +$$ (With $$M_0 = M$$) all symplectomorph too $$M$$"Showing the stretching of the neck" around $$C$$ at the time $$t geq 0$$,

According to the thesis of Evans (E)This process tends to a limit $$M _ { infty}$$ which is obtained from $$M$$ by cutting $$C$$ and sticking the positive / negative part of the symplectization of $$C$$ (In the work it is called as $$Bbb S _ { pm} (C)$$, I believe that this process should similarly lead to a family of Lefschetz fibrations $$E_t$$ about $$M_t$$ and a limiting vibration $$E _ { infty}$$ (I believe we put something trivial on the ends we introduce).

I am interested in understanding the moduli space of pseudo-holomorphic portions of such a vibration. Let's say I have chosen a generic compatible AC. structure $$J$$ and I remember that I have no bubbling due to my accuracy assumption. From my stretching process, a family of manifolds arises $$mathcal {M} _t$$, What can I say about this family of module spaces? How do I deal with the borderline case? $$mathcal {M} _ { infty}$$? Is it somehow a limit to the family of spaces that are parametrized by the positive realities?

I think I can come up with a naïve rationale for my claim, but trying to push it to the limit, I expect many technical issues and I do not know them yet.

Can somebody point out to me if there are obvious obstacles / difficulties in what I am trying to understand and if there is literature that somehow sheds light on what I am trying to understand?

## Air travel – is it safe to buy a plane ticket to fly between Schengen space cities in November with a British airline?

I have to fly between Zurich and Berlin at the end of November, the price for an EasyJet flight is 150, the flight with Lufthansa or Swiss Air 250. Normally I would fly only with the cheapest option, but in this case with EasyJet I'm afraid a British Company may have lost its right to fly between Schengen space airports, even if it came to a violent exit on 31 October. I have not found clear information on what might happen in this case, and I am afraid that the flight will be canceled and I am forced to book a very expensive last-minute flight.

Any thoughts on the risk of buying tickets from a British flag company?
