Recently, when planning a trip to Yellowstone Natl Park, the Grand Loop Rd between Tower Junction and Canyon Village will not be included in any trip due to Google Maps inclusion of a road closure. Even one planning a route directly from Tower Junction to Canyon Village will be directed around the entire rest of the loop excluding the most direct route. Previously (approx. 2 yrs ago), this route was available, as I had planned an extensive trip including this route, and the map included this stretch of road. I am wondering if it has something to do with the “road closure” notice, or labels saying “(Closed winters)”, but other roads in the region (i.e., Norris Canyon Rd) are so labeled but allow planning to use these routes. How does one plan a future trip without consideration of present road closures?

## real analysis – Prove Cantor Function maps rationals to rationals

Let $Lambda$ be the Cantor function and $C$ be the Cantor set. I need to show two things

(1) $Lambda(x) in mathbb Q$ when $x in (0,1)cap mathbb Q$

(2) $x in mathbb Q$ when $Lambda(x) in mathbb Q$ and $x in C$

Not quite sure how to go about this

## real analysis – Is a locally invertible weak limit of injective maps injective almost everywhere?

Let $Omega_1,Omega_2 subseteq mathbb R^2$ be open, connected, bounded, with non-empty $C^1$ boundaries.

Let $f_n:barOmega_1 to barOmega_2$ be Lipschitz **injective** maps with $det(df_n)>0$, and suppose that $f_n$ converges to a $C^1$ function $f: barOmega_1 to barOmega_2$ **weakly** in $W^{1,2}$, and that $det(df)>0$ everywhere on $barOmega_1$.

Is it true that $|f^{-1}(y)| le 1$ a.e. on $Omega_2$?

Does the answer change if we assume in addition that $f_n|_{K} to f|_{K}$ **strongly** in $W^{1,2}$ for every $K subset subset Omega_1$?

## Limit of waypoints in Google My Maps

I recently found out you could make maps in Google My Maps to track the route you took.

I want to map out the driving directions I took for a trip a few years ago, but I am **only** able to add **10** waypoints though (A – J), then I had to make a new grouping/batch of directions.

I was wondering if it was possible to add more destinations direction/points then just 10?

In the photo attached, I want to merge the two groups of directions into one big list.

## What is the name for a functor preserving open maps? Quotient maps? Effective epimorphisms?

How does one call an endofunctor of the category of topological spaces which preserves

open maps? Quotient maps?

More generally, how does one call a functor that preserves effective epimorphisms?

## How to keep a custom map visible during a regular google maps search?

I have a custom map saved. On the computer, I view it by going to `[Hamburger Icon] > Your places > Maps`

. When I click on the map, I can see the places on that map. But I want to search hotels near some of those places, and I can’t figure out how. When I hit the back arrow, the map disappears. How can I keep my custom map visible during a normal Goole maps search? Surely this has to be possible…

I recently found out you could make maps in Google my maps to track the route you took.

I have a question regarding making maps. That would be awesome if anyone could help me.

## usability – Interactive maps using d3?

I’m a freshman interaction design student in a Web Development I class. I have a pretty strong understanding of HTML& CSS already, but I have never used JavaScript. My professor asked me to lead a special web design project that will involve creating interactive maps to render economic related data.

Here are some requirements for the project:

```
• The local map (comprised of 2 counties) will include a visualization of: foreign direct investments per county (per year), exports by industry per county (per year)
• The world map will 1 map will provide a visualization of: export value to foriegn nations, import value from foriegn nations, service export value to foriegn nations , (all per year)
• Each map will pull from a JSON database that will be compiled for me.
• As the user mouses over each county or country, a popover including the $ value should appear.
• I need create the SVG containers and properly position the data within the containers.
• I would like to add drop down or radio options for each map that will includethe ability to switch between the sets of data. such as: years, exports, foriegn direct investments, etc.
• I also believe I should create a drop down or some type of list allowing the user to choose the specific country or industry they wish to find without having to click on the map.
• I would like to color the areas of the map according to each value, for example: light blue for $100M - dark blue for $100B.
```

I have been reading about JQuery on W3 Schools, I have watched multiple YouTube videos on how to use D3, and I tried it myself using some examples on GitHub. I have not received the data yet, but I do want to understand what my limitations are before I start the design for the rest of the website, so I will be trying out a csv file from the census to start learning how to position the elements within the container.

My question is, does anyone have experience creating similar maps? I have read through other threads here, and it’s given me a better understanding. However, I still feel a little lost. Does anyone know of any resources I could use to learn more?

I know this question is a bit vague, so I understand if there isn’t much to say. But really, I am just relieved that there is a place for me to even ask it! So, thank you for your time!

## reference request – Stratification of the space of maps transverse to another given one

If $M,N,S$ are manifolds ($M$ and $S$ compact) and $g:Sto N$ is a smooth map, then if we endow $C^infty(M,N)$ with the strong topology we get that

$$pitchfork(M,N;g):={fin C^infty(M,N),;,fpitchfork g}$$

is dense and open in $C^infty(M,N)$ (see Hirsch, Differential Topology, and Kosinski, Differential Manifolds). This indicates that $pitchfork(M,N;g)$ would fit to be the $0$-stratum of some stratification on $C^infty(M,N)$.

I would be interested to know if someone already established such stratification, with a particular interest in the description of the $1$-stratum he or she came with. I am also very interested if the article discusses how a generic path $f_tin C^infty(M,N)^{(0,1)}$ behaves with respect to this stratification. Thanks for your help!

## samsung – Remove email Contacts from Maps quick share

How do I remove the email contacts from my quick share in google Maps? I DO NOT want one the people shown in the picture to be there. I do not have them saved as a contact either in my phone nor in my gmail, but I have to email them regularly… But it is unpleasant, and I don’t want to have to look at them just anytime I try to share my map. Please help me.
